Abstract

This paper focuses on improving the signal-to-noise plus interference ratio on multi-input multi-output radars. Here, an algorithm is proposed, whereby the waveform of the transmitter and the receiver filter coefficients are designed simultaneously to better detect the targets in the presence of the dependent interference signal. The proposed algorithm is a convex optimization-based sequential algorithm, in which each iteration optimizes the Covariance matrix of the transmitted signals to concentrate the antenna radiation pattern on the target and also attempts to eliminate the maximum number of interferencein the receiver. The problem is in addition to limiting the use of identical RF circuits to all transmitting antennas, with the limitation of minimum interference power for each target. In previous research this scheme was designed to intercept a target, but in this study the Covariance matrix is designed to maximize the signal-to-noise and interference ratio and the antenna transmit power at the maximum position of all targets and at the interference position as low as possible. The simulation results also show that the proposed method can achieve the maximum signal-to-interference plus noise ratio in all targets. This value can also be increased by increasing the number of antenna elements.
