摘　　要：针对遗传优化算法获取正交相位编码信息的运算量较大和频率复用方式频带资源消耗过多的问题,设计了一种超宽带MIMO雷达波形。基于伪随机序列的统计特性和窄脉冲的超宽带优势,设计性能优良的正交波形,并比较不同波形设计方式下MIMO雷达成像效果。仿真结果表明,基于伪随机序列的超宽带MIMO雷达波形的运算量和成像分辨率都优于传统MIMO雷达。For the problem of genetic optimization algorithm for orthogonal phase encoding information computational cost is larger and the way of frequency multiplexing frequency band resource consumption is too much, an ultra-wideband MIMO ra- dar waveform is designed. Based on the statistical properties of pseudo-random sequences and the advantage of ultra-wide- band pulses, the orthogonal waveform with excellent properties is designed, then the MIMO radar images are compared un- der different waveform design methods. Simulation results show that ultra-wideband MIMO radar based on pseudo-random sequences is better than the traditional MIMO radar in waveform computation and imaging resolution.
