False track discrimination in the sidelobe region of a monopulse antenna.

摘要: A radar target discrimination method (50) prevents sidelobe monopulse tracking. The beamwidth difference between the main beam and is utilized to distinguish tracks from tracks. After first (52), moved (58) two additional pointing angles such that will stay on same side of true slope but fall opposite slope. sign magnitude difference/sum (Δ/Σ) measurements (56, 62, 64) can be used (66) a valid track false track. If signs for three are not same, potential rejected. magnitudes do increase or decrease monotonically, depending relative power measurement,
