Abstract
To deal with the threat of the new generation of electronic warfare, we establish a non-cooperative countermeasure game model to analyze and interference suppression between multistatic multiple-input multiple-output (MIMO) radars and in this study. First, according to the strategy, a supermodular game framework with a fixed weight (FW) vector is constructed. At the same time, a constrained optimization model for maximizing the radar utility function is established. Based on the utility function, the best strategies for the radars and jammers are obtained. The existence and uniqueness of the Nash equilibrium (NE) of the are proved. A algorithm with FW is proposed which converges to the NE. In addition, we use adaptive methods to suppress cross-channel interference that occurs as direct wave interferences between the radars and jammers. A algorithm for joint and is also proposed. The algorithm can ensure the best , and also improves the interference suppression ability of the . Finally, the effectiveness and convergence of two algorithms are verified by numerical results.
