| 摘 要： | 该文采用跳频脉冲信号作为成像雷达信号形式,研究了一种雷达等效转台目标距离-多普勒成像的新算法。与常规步进频率雷达傅里叶变换成像算法相比,该算法具有多普勒不模糊范围大的特点,因而克服了步进频率雷达成像算法容易产生多普勒混叠的缺点。计算机仿真结果表明了该算法的有效性。

| Abstract: | With adoption of the hopped-frequency pulses as a radar waveform for imaging targets, a novel algorithm for range-Doppler imaging of rotating targets is proposed. Compared with the stepped-frequency radar Fourier transform (FT) imaging algorithm, the algorithm is characterized by large unambiguous Doppler window that eliminates Doppler confusion occasionally arising via the stepped-frequency radar FT imaging algorithm. Computer simulation results are given to confirm the effectiveness of the proposed algorithm. |
