Waveform Design For MIMO Radar Systems
Subject area: Science,Engineering and Technology · Area of research: Electrical and Electronic engineering
Abstract
Waveform design is critical to the realization of a Multiple Input Multiple Output (MIMO) radar system. If the wave forms being transmitted are perfectly orthogonal, the virtual array consists of more elements than the transmit array and this provides additional degrees of freedom which improves performance. The correlation properties of the wave forms transmitted determine the characteristics of the system. In this paper, a binary orthogonal waveform with low auto correlation and cross correlation properties is designed. Orthogonality in transmitted wave forms is required in MIMO radar systems to enable the use of match filtering at the outputs to separate the different transmit paths. Exploiting the orthogonality of the walsh hadamard matrix based on non identical walsh functions, the simulated annealing statistical optimization tool is used to obtain the orthogonal signal set with the desired low correlation properties.
