Drones and military aircraft try to hide their real positions through deception jamming. The following videos show successful detection with pulse compression and alternatively pulse Doppler, and subsequent detection algorithms.
Detecting Range Deception with Pulse Compression and Subsequent Algorithms
Left PPI: with a target and no range deception on it. You can see clearly the target, but due to the compression on the pulse, the shape and detected target is not highlighted and a bit degraded in comparison with other pulse radars.
Middle PPI: with a target and range deception on it. after the first time that we saw the target, in the next rotations the target is deceived on it's range trying to shift it as soon as possible out of the line of sight of the radar.
Right PPI: with a target and range deception on it, and the detection of range deception. The "detection of range deception algorithm" detects if a target is deceived on range and then estimates the real/expected position of the target.
Detecting Range Deception with Pulse Doppler and Subsequent Algorithms
Left PPI: with a target and no range deception on it. You can see clearly the target. The image is better as with the pulse compression, because the Pulse Doppler integrates 64 pulses for on frame. This increases the quality of estimation for one frame. Also the high number of pulses which are integrated enable the velocity estimation of the target using the 2D FFT.
Middle PPI: with a target and range deception on it. after the first time that we saw the target, in the next rotations the target is deceived on it's range trying to shift it as soon as possible out of the line of sight of the radar.
Right PPI: with a target and range deception on it, and the detection of range deception. The "detection of range deception algorithm" detects, if a target is deceived on range and then estimates the real/expected position of the target.
There is much more in SkySim
Follow our blogs and videos on SkySim to learn more about the simulator, range deception, angle deception, speed deception, radar lock on and major state of the art defense algorithms against malicious attacks.
Such defense is not only useful in a military context but also in a civil aviation setting. Increasingly speed radar jammers by trucks and cars disturb airport infrastructure.
