Abstract

A radar system operating at a carrier frequency of 500 MHz and using different coded sequences is built and tested at NMSU. A limited set of experimental results at various ranges for both sequences: pseudorandom binary sequences (PRBS) and Golay were obtained and the comparison between them was done. Our tests indicate, though not conclusively, that Golay sequence seems to offer lower sidelobe level than PRBS sequences. Moreover, Golay sequences may yield higher dynamic range and results in improvement in estimation of the delay spread.
