摘要
研究基于DPCA和干涉技术的SAR动目标检测与成像方法,提出了在估计运动目标的径向速度和真实的方位位置的过程中考虑运动目标的方位向速度的影响,导出了估计目标的径向速度和真实的方位位置的表达式,在运算量没有增加的前提下使得动目标参数的估计精度有所提高,从而可以更好的对运动目标进行定位与聚焦成像。给出了应用该方法的具体步骤,通过仿真实验验证了本方法的有效性。
The moving target detection and imaging method based on DPCA and interferometry is studied and improved. The influence of the moving target＇s azimuth velocity is considered in estimating the radial velocity and true azimuth position of the moving target. The expressions of the two moving target parameters are derived. The estimation precision of the moving target parameters using this method is improved without the increase of the amount of computation. The procedure of this method is given and the validity is demonstrated by computer simulations finally.
