摘要
提出了在机载SAR模式下应用三孔径DPCA技术对地面慢速运动目标进行检测与定位的方法、从回波模型入手对此方法进行了理论分析并给出了计算机仿真结果。仿真结果表明,在满足DPCA条件的情况下,系统可以得到理想的主瓣杂波抑制效果和良好的测速定位性能。本文最后给出由于雷达平台的运动误差而导致DPCA条件不满足的情况下该方法的检测、定位性能。
A new method for slow moving targets detection and location in airborne SAR imagery ispresented based on three-aperture DPCA technique. The method is analyzed on the ground of signal model.and the computer simulation results are given. The simulation results indicate that for ideal DPCA, the per-formance of mainlobe clutter suppression and targets location is perfect. The performance curves with sys-tem error are also given in the end of this paper.
