ABSTRACT:
A radar target discrimination method (50) prevents sidelobe monopulse tracking. The beamwidth difference between the main beam monopulse and sidelobe monopulse is utilized to distinguish the main beam monopulse tracks from sidelobe monopulse tracks. After the first monopulse beam (52, 54), the monopulse beam is moved (58) to two additional beam pointing angles such that the target will stay on the same side of the true main beam monopulse slope but will fall on the opposite side of the sidelobe monopulse slope. The sign and magnitude of the difference/sum (.DELTA./.EPSILON.) measurements (60, 62, 64) can be used to distinguish a valid main beam track from a false sidelobe track. False tracks are detected if the signs of the difference/sum measurements are not identical, or if the magnitudes of the measurements do not monotonically increase or decrease.
