Method and device for reducing the power of the interference signals received by the secondary lobes of a radar antenna at random frequency.

摘要

Process and device for reducing the power of the interference signals received by the secondary lobes of a main antenna ap of the radar with random frequency fe (n), which is associated with a plurality of antennas secondary as1.. Asn in which the signals used for the calculation (10) of the weighting coefficients (w1 to wn) to be applied in order to obtain a signal resulting from the weighted linear combination of the secondary signals d1.. Dn to subtract the signal c of the main channel (vpd) relative to the emission frequency fe (n + 1), are those (vo and v1,.. vn) treated in the auxiliary channels, the main (vpa) and secondary (asa1 ,.. asan) relative to the emission frequency fe (n + 1) of the train of recurrences of radar reception during the period of the train of recurrences corresponding to the emission frequency fe (n), for the distance compartments obfuscated selected by the circuit (15). br / application to the radar with random frequency.
