Jammer: The Relentless Killer of Heart Disease in Radar Systems

Radar systems play an extremely important role in modern electronic warfare, but they have also revealed a fatal weakness - their dependence on the Doppler effect. The Doppler Jammer (Doppler jammer) is a “merciless killer” that targets this weakness.

Misuse of the Doppler Filter Vulnerability
Doppler filter is an important part of radar anti-jamming, it can effectively filter out the noise of stationary targets. However, the frequency jammer can accurately simulate the ideal Doppler shift to slip through the filter's defenses.

Accurate Tracking Simulates Real Targets
Doppler Jammer can synthesize the same Doppler shift as the actual target's trajectory, with minor perturbations that make it impossible for the radar system to distinguish between the real and the fake.

Spectral masking invites sensitivity loss
By generating noise that overlaps the target echo spectrum, wifi cellular jammer is able to create spectral masking on the front-end of the radar receiver, which significantly reduces radar sensitivity.

Filter ringing effect depletes dynamic range
By utilizing the ringing characteristics of the Doppler filter, the Doppler Jammer can forcibly induce a ringing effect, which rapidly depletes the dynamic range of the radar receiver and prevents it from tracking the real target.

Automatic Detection and Frequency Shift Avoidance
Doppler car jammer automatically senses and analyzes the characteristics of Doppler filters, and intelligently selects a reasonable frequency shift value to avoid the filter and maximize the interference effect.

Millimeter-wave modulation to avoid detection barrenness
For future millimeter-wave radar systems, UAV jamming device will use advanced amplitude-phase modulation technology to generate strong signals that are completely coherent with the echo signal, leaving the detector barren.

Precisely because of the precise abuse of the Doppler effect of this fatal loophole, Doppler Jammer in electronic warfare role can not be underestimated, it not only makes the radar blind, but also connected to the radar system lifeline of the “hangman”. In the future, with the development of intelligent technology, the Doppler Jammer will surely become a major weapon to counterbalance the power of radar.
