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。

关键词: 低可观测目标, 长时间积累, 硬件实现

Abstract:

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 or some other issues.The existing compensation algorithm has large amount of calculation and fails to keep the balance of performance and computational complexity.This paper presents a method of coherent integration in segment followed by noncoherent integration between segments.It has a good detection performance with lower amount of computation.Tests on hardware show that this algorithm can be efficiently and conveniently applied to engineering implementation.

Key words: low observable target;long time integration;hardware implementation
