| 摘 要： | 针对窄带相参雷达刚性编队目标架次分辨难题,该文提出了基于高分辨Doppler像架次分辨和横向间距定标的方法。首先,建立了基于长时间积累的刚性编队目标信号模型。其次,基于Doppler锐化度准则估计目标切向速度,并通过聚焦处理获取编队目标的高分辨Doppler像。进而,基于目标高分辨Doppler像谱峰个数获取目标架次信息并实现编队目标间的横向间距定标。同时,还定量分析了刚性编队目标可分辨的最小积累时间。最后,用实测窄带雷达数据验证了本文方法的有效性。

| Abstract: | A high Doppler resolution(HDR) image method was developed for sortie determination and cross-range scaling of rigid targets.A signal model was developed for narrowband coherent radar with a long coherent integration time.The cross-range velocity is then estimated using Doppler sharpening to obtain HDR using autofocusing processing.The sorties can then be identified in the image with cross-range scaling.The minimum coherent time is derived for rigid targets.Tests with real data demonstrate the method's effec... |
