Abstract

The radar resource impact of using either linear frequency modulation (LFM) or pseudo-random noise (PRN) waveforms is investigated for the case when the radar duty is a limiting factor. It is shown that for large time-bandwidth and low range sidelobe (RSL) requirements, a PRN waveform can be selected that will not increase the radar duty, while LFM will always increase the radar duty. For low time-bandwidth product and moderate RSL requirements LFM will generally have less impact on radar duty than PRN. For moderate time-bandwidth product requirements the impact will be scenario dependent and the difference in radar duty may be outweighed by other considerations.
PRN和LFM波形的比较及其处理对雷达资源的影响
研究了当雷达占空是一个限制因素时,使用线性调频(LFM)或伪随机噪声(PRN)波形对雷达资源的影响。结果表明,对于大时间带宽和低距离旁瓣(RSL)要求,可以选择不增加雷达占空的PRN波形,而LFM总是增加雷达占空。对于低时宽积和中等RSL要求,LFM通常比PRN对雷达工作的影响更小。对于中等时间带宽产品要求,影响将取决于场景,雷达工作的差异可能被其他考虑因素所抵消。
