摘要

本文研究了机载合成孔径雷达(SAL)中三种调相信号的性能。研究了这些信号的收发方式和成像处理方法。考虑到机载SAL的波段很窄，为了降低宽带信号的AD采样率，提出了一种基于线性调频(LFM)信号的相位调制信号的“相位解调”接收方式。对这三种调相信号的成像仿真结果验证了该方法的有效性。

Performance Analysis and Image Processing of Phase-modulated Signal on Airborne Synthetic Aperture Ladar

: In this study, the performance of three phase-modulated signals used in airborne Synthetic Aperture Ladar (SAL) is investigated. The transmitting and receiving modes and imaging processing methods for these signals are studied. Considering that the swath of the airborne SAL is very narrow, in order to reduce the AD sampling rate of the wideband signal, a “phase-dechirping” receiving mode is proposed for the phase-modulated signal based on the Linear Frequency Modulation (LFM) signal. The imaging simulation results for these three phase-modulated signals validate the effectiveness of the proposed method.
