Abstract

A radar including a plurality of antenna arrays (B, . . . , J), for example linear arrays, the reception of electromagnetic waves being coherent for each antenna element in each array. The extraction of target signals from sidelobe signals according to the invention is obtained by comparing the signals received by the various arrays. A statistical processing allows to eliminate the responses corresponding to the array sidelobes. The invention is mainly applicable to radars including a plurality of linear lacunary antenna arrays with an isotropic disposition in space.
