| 英文摘要 | 研究了一种基于子脉冲去斜的高分辨距离像合成新方法。首先,用本地参考信号对接收的步进频脉冲串信号进行去斜处理,然后把去斜之后的信号按顺序在时域上拼接起来得到宽带回波,最后按传统的处理方法得到目标的一维距离像和二维逆合成孔径雷达像。这种方法避免了传统时域拼接法的上采样、频移和相位补偿运算,减小了处理复杂度,易于工程应用。; A novel method for synthesizing the high resolution range profile(HRRP) with respect to the stepped frequency waveforms,which is based on dechirp processing,is proposed.First,the received stepped-frequency pulses are dechirped by local reference signals.The wideband echoes are obtained by joining the dechirped pulses in order in time-domain.Finally,the 1-D HRRP and the 2-D inverse synthetic aperture radar(ISAR) images can be obtained according to the traditional processing.The up sampling,frequency shift and phase compensation operations are avoided with this new method,thus the processing complexity is reduced and this new method is easier to implement in radar systems. |
