| 摘 要： | 阐述了基于距离多普勒算法的线性调频信号体制逆合成孔径雷达(inverse synthetic aperture radar, ISAR)成像原理和间断信号相位补偿原理,在此基础上,针对ISAR谱图特性提出了一种利用波形评价准则和遗传算法进行相位近似补偿的谱图拼接处理方法,并进一步利用拼接后的谱图实现最终的ISAR成像。仿真实验结果表明,该谱图拼接方法简单易行,且可以明显改善ISAR成像效果,具有一定的实用性。

| Abstract: | The theory of inverse synthetic aperture radar(ISAR) imaging with chirp signals based on range-Doppler algorithm and the principle of phase compensation for intermittent signal connection are analyzed.On the basis of that,aiming at the character of the ISAR spectrogram,a novel method of connecting different spectrograms via compensating phases approximately with waveform evaluation criterion and genetic algorithm is proposed.Furthermore,the final ISAR image can be achieved by using the connected spectrogram... |
