Abstract

The invention discloses an optimal power control method for a radar-communication integrated system based on radio frequency stealth. The radar-communication integrated system comprises M<T> transmitters, a radar receiver and a communication receiver. The method comprises the following steps: S1, characterizing target detection performance; S2, characterizing communication performance; S3, establishing an optimal power control model of the radar-communication integrated system according to a given communication rate threshold r<com>, a false alarm probability threshold delta<FA> and a target detection probability threshold delta<D> to obtain the optimal radar signal transmission power; S4, building a Lagrangian multiplier formula to obtain optimal communication signal transmission power; and S5, adding the optimal radar signal transmission power obtained in the step S3 and the optimal radar signal transmission power obtained in the step S4 to obtain the minimum total transmit power ofthe radar-communication integrated system. The optimal power control method improves the radio frequency stealth performance of the system.

Description

technical field [0001] The invention relates to the field of radar signal processing, in particular to an optimal power control method of a radar-communication integrated system based on radio frequency stealth. Background technique [0002] Under the conditions of modern high-tech warfare, any single electronic equipment or simple superposition of multiple electronic equipment is difficult to deal with the enemy's comprehensive high-tech electronic weapons, and it is difficult to ensure effective and reliable communication, detection and suppression. In order to adapt to the requirements of the modern warfare environment, it is necessary to carry out comprehensive and integrated design of many electronic equipment on the modern combat platform. The integration of electronic equipment not only helps to organically combine different types and different purposes of electronic equipment, facilitates real-time coordination and control of the work of electronic equipment on comba...
