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 disposit...
[ What is claimed is:] [1.] A method for extracting target information from a radar signal produced from a plurality of sparse antenna arrays, each array having sidelobes fixed in azimuth, and which do not overlap, comprising the steps of:receiving radar signals in said sparse antenna arrays;comparing said radar signals received by each of said sparse arrays, to eliminate those radar signals which correspond to radar signals detected only in some of said sparse arrays which are likely to correspond to signals received in array sidelobes; andextracting ta...
