The Estimation of Precession Character Based on Multi-LOS HRRP

Abstract:

In this paper, we use the cone as the model of the warhead to analysis its precession character and target character, which will affect the HRRP (High Resolution Rang Profile) of the warhead. What’s more, we build a model to simulate the situation when the target is observed from multiple line-of-sight (multi-LOS) of radar. After all the research, we come up with an arithmetic that joins precession character and structure character which are based on the multi-LOS time-HRRP. This arithmetic uses all the information that received by radars simultaneously, which can improve the accuracy of the estimation. The simulation experiment indicates the effectiveness of the arithmetic.
