摘要
The radar comprises an adaptive filter (FA), a spectral analyser (AS) and a false alarm rate detector (DT) as well as a circuit for removing ambiguity (LA). The circuit also includes a device for estimation (fc) of the average of the confusion in a region surrounding the processed resolution cell. A TV circuit derives a validation signal (VAL) w.r.t. the average of the confusion and the ambiguous Doppler echo (fi) for each value of the repetition frequency. When the absolute value of the difference is less than a predetermined value for all repetition frequencies, the target is invalid. ADVANTAGE - System reduces number of false alarms caused by search radar.
