China Says New Tech Can Detect Stealth Jets Including F-22, F-35

Chinese sources claimed in May 2019 that a distributed meter-wave radar could detect and track stealth aircraft such as the F-22 and F-35, and potentially provide missile guidance. The public reporting does not independently verify detection performance, fire-control accuracy, or a successful engagement against either aircraft. The story is therefore best understood as a claimed counter-stealth radar design—not proof that China had demonstrated a complete system for shooting down those jets.

What China actually claimed

Futurism’s May 29, 2019 report summarized claims first described by China’s state-run Global Times. Global Times interviewed Wu Jianqi, identified as a senior scientist at the state-owned China Electronics Technology Group Corporation (CETC).

According to that account, Wu’s team developed a meter-wave sparse-array synthetic impulse and aperture radar. The reported layout used multiple transmitting and receiving antennas, each described as tens of meters high, distributed over distances ranging from tens to hundreds of meters. Echoes arriving from different directions would be combined with signal-processing algorithms to improve tracking and estimate a target’s coordinates.

Why meter-wave radar is relevant to stealth

Most fighter stealth measures are optimized against the microwave frequencies used by many conventional fire-control radars. Longer meter-wave transmissions interact differently with an aircraft’s size and shape, so a stealth design that greatly reduces returns in one frequency band may still produce detectable signals in another.

The trade-off is that meter-wave systems have traditionally offered poorer resolution and positional accuracy than shorter-wavelength radars. A radar may indicate that an object is present without producing the precise, stable coordinates needed to aim a missile. Global Times presented the distributed array and its processing algorithms as an attempt to reduce that weakness.

Chinese military analyst Wei Dongxu told Global Times that the approach could improve continuous tracking and potentially guide long-range missiles. That is an assessment quoted by the outlet, not an independently measured result.

Detection is not the same as a missile hit

Counter-stealth discussions often collapse several different tasks into the single word “detect.” They are separate links in an air-defense kill chain:

Step What it requires What the 2019 reporting establishes
Detection Recognizing a possible object in radar returns Chinese sources claimed the meter-wave system could do this against stealth aircraft.
Continuous track Maintaining a reliable position and velocity estimate as the aircraft maneuvers Chinese sources described this as an intended advantage; no independent performance data was provided.
Identification Determining that the return is the relevant aircraft rather than clutter, decoys or another platform Not demonstrated in the public sources.
Fire-control solution Generating sufficiently accurate coordinates for a weapon or interceptor Global Times reported a missile-guidance claim, but supplied no independently verified accuracy result.
Weapon engagement Completing the attack despite maneuvering, countermeasures and sensor or communications losses No cited public report documents a successful engagement of an F-22 or F-35 by this system.

The F-35 Joint Program Office makes the same distinction in its discussion of stealth. Retired Marine Corps Major Dan Flatley said that an adversary must build a complete kill chain: “just because a radar can find an object — and VHF radars can spot F-35s — doesn’t mean it can fix, track, target, and consummate that kill chain with a missile hit.”

What the distributed array was intended to solve

More useful geometry

Using separated transmitters and receivers allows a target to be observed from multiple directions. In principle, those different paths can provide more information than a single compact antenna, particularly when the target’s radar signature changes with aspect.

Signal processing rather than a magic frequency

The reported concept depends on combining echoes and applying algorithms to synthesize a larger effective aperture. The claimed improvement therefore comes from the whole sensor network and its processing, not simply from operating at meter-wave frequency.

The unresolved engineering costs

A network spread across tens or hundreds of meters needs precise timing, calibration, communications and protection. Large exposed antenna structures can be easier to locate and attack. The National Interest also identified jamming, spoofing and the vulnerability of large arrays as issues that would affect real-world performance.

What remains unproven

  • No independently verified detection range, tracking accuracy, refresh rate or coordinate error was published in the cited accounts.
  • No evidence establishes that the system maintained a track on an operational F-22 or F-35 under realistic clutter, electronic attack or changing geometry.
  • The reports do not show that the radar alone supplied a fire-control-quality solution to a missile battery.
  • There is no reported combat test or successful missile engagement attributable to this system.

Wu Jianqi told Global Times: “As for now, I do not see a meter wave air defense radar from abroad that can match the criteria of the advanced meter wave radar [like the one China has].” That is Wu’s comparative claim, not a third-party evaluation.

How this claim compares with other counter-stealth approaches

Different technologies address different parts of the problem, and public reporting does not provide a common performance baseline for them.

Approach Primary mechanism Evidence relevant here Key unanswered question
2019 CETC meter-wave radar claim Long-wavelength distributed active radar and signal processing Design description and claimed missile-guidance potential Can it deliver a resilient fire-control track?
Conventional microwave radar Shorter-wavelength active radar Not a performance comparison in the cited reports How does the target’s aspect and stealth shaping affect detection?
Passive sensing Uses external transmitters and observes disturbances or reflections No system-specific result provided Can it maintain accurate tracks without its own illuminator?
Infrared sensing Detects thermal emissions rather than radar reflections Separate 2026 laboratory report concerned simulated F-22/F-35-like heat signatures How would weather, range and aircraft operating conditions affect a real track?
Quantum-radar claims Quantum-enabled sensing concepts Separate 2026 reports noted Chinese production claims alongside technical skepticism Is there an operational advantage under field conditions?

These categories should not be treated as interchangeable evidence. A laboratory result, a proposed architecture, a field trial and an operational engagement demonstrate different things.

Do not confuse the 2019 radar story with later reports

Quantum radar

A 2026 U.S. Army Training and Doctrine Command OE Watch item discussed Chinese media claims about production of quantum-radar components while noting practical barriers and technical skepticism. That is a later and distinct technology story, not evidence that the 2019 meter-wave array achieved operational performance.

Infrared AI

A separate August 2026 South China Morning Post report described an AI model recognizing simulated F-22- and F-35-like infrared signatures with more than 90 percent accuracy in laboratory testing. Simulated thermal targets are not radar detections of operational aircraft, and that result should not be attributed to the 2019 CETC system.

Bottom line for the F-22 and F-35 headline

China’s 2019 claim was technically plausible enough to merit discussion: meter-wave radar can detect objects that are difficult for some microwave radars, and a distributed array could theoretically improve the accuracy problem. But the available public evidence stops at a source-reported design and assertions by Chinese officials and analysts. It does not establish independently verified detection, a continuous track, a fire-control solution or a missile hit against an F-22 or F-35.

Frequently Asked Questions

Was a Chinese meter-wave radar shown shooting down an F-22 or F-35?

No. The public reports describe claimed capability and potential missile guidance, but do not document an independently verified engagement against either aircraft.

Why can a radar detect a stealth aircraft without being able to attack it?

Detection can provide only a coarse location. An air-defense system still needs a stable track, identification, precise fire-control coordinates, a functioning communications chain and a weapon that can complete the engagement.
