Joint frequency-hopping waveform design for MIMO radar estimation using game theory

Using a colocated Multiple Input Multiple Output (MIMO) radar system, we consider the problem of joint design of amplitudes and frequency-hopping codes for frequency-hopping waveforms. First, we present the MIMO radar signal model and the sparse representation. Then, we formulate a novel game model and propose two joint design algorithms, one applying a non-cooperative scheme, and the other applying a cooperative scheme. Owing to the extremely large size of the feasible set of the discrete code, we propose to use these algorithms to obtain the ε-approximate Nash equilibrium (ε-ANE). We demonstrate the improvement of the resulting codes and amplitudes through numerical examples.
