摘    要:在多频连续波雷达多目标参数测量中,目标速度、加速度的准确快速估计对后续测距、测角有重要的意义.小波变换是时频分析的有力工具,能方便、准确和快速分析目标的时频参数.通过检测时频面上的直线,可以准确的得到目标参数.小波变换满足线性叠加,小波变换具有良好的多目标处理性能,对多频连续波雷达多目标信号处理具有良好的适应能力.研究了基于小波变换的雷达多目标速度和加速度估计算法:通过小波变换提取小波脊线,估计出高能量目标参数,然后构造陷波滤波器滤掉该目标信号,通过上述方法逐步估计出剩下目标参数.仿真试验表明了该算法的有效性.

关 键 词:多频连续波雷达  加速度、速度估计  小波变换  多目标信号

Abstract:In multi-frequency CW radar,estimating velocity accurately is important to acquire their parameters.Acceleration and velocity of radar's target can be detected from time-frequency curve of radar's echo.Wavelet transform is a good skill for time-frequency analysis.It can detect target parameter of time-frequency easily and fast.By detecting beeline perfectly,the parameters of linear signals can be obtained exactly.Wavelet transform is a linear transform and is a good tool for estimating parameters of multi-f...
Keywords:Multi-frequency continuous wave radar  Acceleration and velocity estimation  Wavelet transform  Multi-component signals
