Abstract

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.
