Abstrak

In this paper, the clutter rejection threshold corresponding to the maximum Doppler frequency of mainlobe clutter in high pulse repetition frequency airborne radar with frequency modulation (FM) ranging is proposed. The clutter spreading due to range-Doppler coupling in FM ranging radar is analyzed, and based on that, four clutter rejection thresholds corresponding to the maximum sidelobe/mainlobe clutter frequencies without/with FM ranging are presented. In particular, the clutter rejection threshold for achieving mainlobe clutter-free condition with FM ranging is derived by analyzing the mainlobe clutter boundaries for various beam steering angles. The detection capability corresponding to each of the four thresholds is analyzed, and it is shown that the detection capability can be improve by applying the clutter rejection threshold proposed in this work.
