| 摘要: |
| 在线性调频连续波(LFMCW)雷达中,加速度运动目标回波存在多普勒频谱畸变现象,造成目标检测性能和参数估计精度损失。本文提出对同一距离单元上的多个目标的多普勒信号进行修正的多项相位变换,能够以较小的运算量,准确估计多个目标的速度和加速度,达到改善目标的检测性能和提高参数估计精度目的。 |

|
| () |
| Abstract: |
| In LFMCW radars,the echo signal of moving target with acceleration has Doppler aberration which will cause the detection performance and parameter estimation loss of target.This paper presents that using the Modification Polynomial Phase Transform(MPPT) to process the Doppler signal of multi-targets in the same range cell can estimate the acceleration and velocity of multi-target precisely and improve the detection performance and parameter estimation precision at the cost of less computation. |
| Key words: LFMCW radar,Modification Polynomial Phase Transform(MPPT),Multi-target,Velocity estimation,Acceleration estimation |
