Abstract
In recent years, orthogonal frequency division multiplexing (OFDM) has been widely used as a radar communication integrated shared signal. In order to improve the RF stealth performance of OFDM radar communication integration system, a shared waveform optimization method based on interception probability is proposed. Firstly, the interception probability model of the interception receiver for OFDM shared signal is derived, and then the resource management model of OFDM radar communication integration system is established. The objective function of the model is to minimize the probability of interception, and the constraint conditions are radar mutual information and data information rate, that is to say, under the condition of certain mutual information threshold and data information rate threshold, the convex optimization method is used to optimize the design of OFDM shared signal waveform. The simulation results show that the interception probability can be effectively reduced by reducing the threshold value of mutual information and data information rate.
