Method and device for the reduction of the power of the interference signals receipts by the secondary lobes of a radar antenna

摘要

This reduction of the power of the interference signals receipts by the secondary lobes of a radar antenna, which is associated an auxiliary plurality of the antenna according to which the signals used for calculating the coefficients of weighting (wi) is applied in order to obtain a signal obtained by means of the combination of linear weighted 19 of the auxiliary signals to subtract 21 of the signal of the main channel, are gotten rid of the interference signals, which is constituted mainly by the fixed echo 13, 131, 132, 133, and the thermal noise 25, 251, 252 and 253, the siganux indicating the boxes obfuscated being then those obtained at the end of the recurrence. / p & & p & application to the radar comprising a device for the reduction of the power of the interference signals of the type of secondary lobes (ols).
