Radar sensitivity and resolution in presence of range sidelobe reducing networks designed using linear programming

The design of a sidelobe-reduction network for coherent high-resolution radars using Barker codes and the results of an analytical investigation of its performance are presented and illustrated graphically. Compression is achieved by a matched filter followed by a weighting network designed using linear programming to minimize the implementation to adapt to different operating modes. It is found that the network gives significant increases in sensitivity and resolution while limiting mismatching losses to about 0.2 dB. A typical digital implementation requires only 66 devices for 10-bit input and sampling rate 150 nsec.
