| 摘 要： | 根据运动目标在宽带线性调频脉冲照射下的回波特点,提出了一种采用宽带单个脉冲对运动目标测速和测距的方法。该方法首先对回波信号进行STRETCH处理,然后对处理后的回波进行快速解线性调频,并用ESPRIT方法取代传统的FFT方法,从而大大提高了参数估计精度,实现了采用宽带单个脉冲对运动目标的同时测距与测速。仿真试验表明该方法具有良好的测量精度。

| Abstract: | Based on the analyzing signature of wideband echo of moving target, a novel method is proposed, which can measure range and velocity of moving target simultaneously by employing single wideband pulse. High - resolution radar echo is processed with STRETCH technique and then the fast dechirp algorithm is used to estimate the parameter of echo signal. By adopting ESPRIT algorithm instead of FFT algorithm, the precision of frequency estimation is improved. Simulation results show that this method can obtain high measure precision of range and velocity. |
