Research on LRCS Simulation for Laser Radar Target with Micro-motion

Laser Radar(LADAR) is a sensitive Radar which can obtain high measurement resolution that might be hardly achieved by the microwave Radar. More Doppler frequency shift and more geometric structure information can be obtained by using LADAR in detection of target with micro-motion. According to the micro-motion model of target, an algorithm based on the graphical electromagnetic computing(GRECO) is proposed for the dynamic LRCS simulation of complex target. The LRCS of each small triangular plane element is calculated firstly and then summed for a total LRCS of the whole target. The examples of simulation result in various micro motion forms are given and the results match well with the theoretical results.
