本文介绍了一种波形评估和选择策略(ESS),用于应用优化的调相(PM)波形来抑制雷达中的复合高斯杂波。该策略解决了PM波形的自适应设计在检测性能方面的潜在改进和由此带来的系统资源成本之间的权衡。引入了一个评估因子来量化在两级杂波抑制方案的第二子驻留中设计和传输优化的PM波形与在子驻留中使用线性调频(LFM)波形相比所获得的性能改善。该评价因子为所提出的ESS提供了依据,其有效性在仿真中得到了验证。
This correspondence introduces a waveform evaluation and selection strategy (ESS) for application of optimized phase-modulated (PM) waveforms to mitigate compound-Gaussian clutter in radar. This strategy addresses the trade-off between potential improvement in detection performance from adaptive design of PM waveforms and the cost this entails in terms of system resources. An evaluation factor is introduced to quantify the performance improvement obtained by design and transmission of an optimized PM waveform in the second sub-dwell of a two-stage clutter mitigation scheme versus using linear frequency modulated (LFM) waveform in a sub-dwell. This evaluation factor provides the basis for the proposed ESS, the efficacy of which is demonstrated in simulations.
