为去除外弹道测量数据中的噪声,分析小波变换用于外弹道测量数据处理的基本原理,结合某新型雷达和弹种的参数进行弹道测量数据仿真,用小波变换的方法对仿真数据进行处理,并与Kalman滤波方法的结果进行比较。仿真结果表明在弹道模型未知的情况下,小波滤波方法的精度更高,战场实用性更强。

In order to remove the noise of external trajectory measurement data, the principle of external trajectory measurement data was presented based on wavelet, and simulation was conducted by means of parameters of a new type of radar and cannonball, the simulation data was processed by the wavelet transform method and was compared with the result of Kalman filtering method. Simulation results indicate that the precision and practicability of wavelet transform method are better than Kalman filtering method when the trajectory model is unknown.
