The interrupted transmitting and receiving (ITR) can be used in anechoic chamber to solve the coupling between the transmitted and reflected signals. When the ITR periods are random, the fake peaks in high-resolution range profile (HRRP) of ITR echo can be reduced. Then, by utilizing the piecewise sparse property of ITR echo, the HRRP is reconstructed based on compressive sensing (CS). However, the periods of ITR determine the restricted isometry property (RIP) condition and the HRRP reconstruction performance. In order to improve the HRRP reconstruction performance, the ITR period sequence optimization method based on a genetic algorithm (GA) is proposed in this paper. The correlation coefficient of the sensing matrix columns is minimized after optimization so that the RIP of the sensing matrix can be well satisfied. Simulation and comparison results illustrate that the optimization method converges fast and the HRRP reconstruction performance is improved with the optimized ITR periods.

中断的发射和接收（ITR）可以在消声室中使用，以解决发射和反射信号之间的耦合问题。当ITR周期随机时，可以减少ITR回波的高分辨率范围轮廓（HRRP）中的假峰。然后，利用ITR回波的分段稀疏特性，基于压缩感知（CS）重建HRRP。但是，ITR的时间段决定了受限等轴测特性（RIP）条件和HRRP重建性能。为了提高HRRP的重建性能，提出了一种基于遗传算法的ITR周期序列优化方法。优化后将感测矩阵列的相关系数最小化，从而可以很好地满足感测矩阵的RIP。
