MIMO Radar Waveform Design for OFD-LFM with Various Frequency Steps

摘要

摘要: 正交频分线性调频(OFD-LFM)信号是多输入多输出(MIMO)雷达的一种常用发射波形，在分析其空时特性的基础上，针对空域合成信号自相关旁瓣存在的问题，该文提出一种非均匀间隔的OFD-LFM波形，并给出了相应的波形设计方法。该方法建立空时联合优化的模型，采用序列二次规划求解得到各信号的频率间隔和初相。所设计波形的发射方向图近似全向，空域合成信号具有良好的相关性能。

Abstract: Orthogonal Frequency Division-Linear Frequency Modulation (OFD-LFM) signal is widely used in Multiple Input Multiple Output (MIMO) radar systems. For solving the problems of the auto-correlation sidelobes of the spatial synthesized signals, an analysis is made of the inherent sidelobe property. Furthermore, OFD-LFM with various frequency steps is proposed and the waveform design method is given. The optimization model is established based on the temporal property and spatial property jointly. Then, the frequency steps and initial phases are optimized by Sequential Quadratic Programming (SQP). The transmitted power of the designed waveform is approximately equal in all directions, and the spatial synthesized signals have good correlation properties.
