摘要
舰船目标的雷达回波经脉冲压缩、MTD后形成RD图,一般使用回波信号的最大值点作为跟踪点,但舰船目标一般要跨越几个多普勒单元,选信号的最大点作为跟踪点不能完全使用RD图信息,而合理使用RD图信息才可减小目标的幅度起伏、角闪烁等的影响,为此本文研究了在RD图上区域加权跟踪点选择方法。实验说明:当目标有起伏或角闪烁时,本文方法优于最大值法。
The radar echo of ship target by the pulse compression、MTD and formed the RD map,that generally use of the maximum of echo signal point as tracking points,but the ship target generally across several Doppler filter,select the maximum point as the tracking points that can not fully use the information of RD map,the rational use of the information of RD map can reduce the impact of the target echo fluctuations or glint,so that study area weighted as tracking points in the RD map.Experiment description: when t...
