Waveform design with good correlation properties for MIMO radar

For multi-input multi-output (MIMO) radar system, the orthogonal waveform set plays important rule to the system´s performance. This paper considers the design problem of orthogonal phase-modulated waveform set with low autoand cross-correlation side-lobes in a specified lag interval. After formulating a multi-dimensional optimization problem, we propose a new iterative approach that based on the pattern search (PS) method. Capabilities of the PS algorithm and the WeCAN are evaluated via numerical simulations. Simulation results indicate that the new method has better performance with respect to the side-lobe level in the specified lag interval and less computation load compared to the WeCAN algorithm.
