摘要
长时间积累是检测低可观测目标的一种有效方法,可利用一段时间内的目标能量来提高信噪比,增加雷达威力。但长时间积累带来了距离走动、多普勒扩散等问题,现有的补偿算法运算量大,无法解决性能与运算量的平衡。文中提出了一种段内相干积累段间非相干积累的方法,其具有良好的检测性能和较低的运算量,算法通过在硬件上测试证明,可高效简便地应用于工程实现。
Long time integration is an effective way to detect low observable targets by making use of the target energy during a period of time to improve the SNR and increase the coverage of the radar at the same time. But a long integration time causes range migration, Doppler spread rithm has large amount of calculation and fails to keep This paper presents a method of coherent integration in or some other issues. The existing compensation algo- the balance of performance and computational complexity. segment followed by noncoherent integration between seg- ments. It has a good detection performance with lower amount of computation. Tests on hardware show that this algo- rithm can be efficiently and conveniently applied to engineering implementation.
