基于压缩感知的多目标认知成像方法
Method of Multi-target Cognitive Imaging Based on Compressed Sensing
摘要
Abstract
In order to realize the real-time high resolution imaging of multi-ISAR targets by utilizing the finite radar resource, this paper puts forward a method for high resolution imaging of phased array radar using the multi target sparse aperture cognition based on compressed sensing. On the basis of cognition of target sparse features, the dynamic allocation function of radar resources is set up based on the targets’lateral sparseness and imagination accumulation time, and the assessment standards for imaging quality are given, thus eventually achieving the high resolution cognitive imaging of various ISAR targets on the condition of finite radar resources. Simulation results indicate that the imaging using this proposed method can not only reduce the pulse numbers for radar imaging, but also shorten the observation time of radars effectively, and meanwhile achieve the target’s ISAR image with high quality.关键词
