Abstract

The invention discloses a method for calculating the mutual information and detection probability of a cooperative MIMO radar communication integrated system, belongs to the technical field of radar communication integration, and particularly relates to calculation of target detection problems and mutual information in radar communication integration. The mutual information of the communication end of the integrated MIMO system and the target detection probability of the radar end are obtained through calculation, and the method can be used for evaluating the performance of the cooperative MIMO radar communication integrated system. According to the method, the MIMO radar system and the MIMO communication system do not depend on signals of the other party as interference any more, but areutilized through cooperation, so the performance of the two parties can be improved.

Description

technical field [0001] The invention belongs to the technical field of radar communication integration, and particularly relates to the target detection problem and the calculation of mutual information in the radar communication integration. Background technique [0002] With the development of electronic technology, the integration of radar communication will be an inevitable trend no matter in military field or civilian field. For example, unmanned fighter jets in the military field not only need to complete tasks such as aerial reconnaissance and battlefield environment monitoring, but also need to transmit the obtained data back to the ground in a timely manner. In the intelligent transportation system in the civil field, intelligent vehicles need to communicate with other vehicles or fusion centers while sensing the surrounding traffic environment, all of which require the equipment to have both radar and communication functions. In an integrated system, because the e...
