Suppressing sidelobe levels in random phase modulated radar

摘要: Signal processing in noise radar is always done by calculating the cross-correlation between transmitted and received signals. Strong echoes of near targets present relatively high sidelobes correlation output, so they can conceal weak (masking effect). Many classical modern methods for alleviating this effect have been offered, however, most them are based on signal receiver side. In paper, a new method waveform design, able to decrease masking effect, presented. Contrary other methods, keeps matched filter structure unchanged does not need performing any extra process This be applied existing concurrently achieve more improvement detection masked targets.
