Radar communication integrated system robust resource allocation method based on radio frequency stealth

Abstract

The invention discloses a radar communication integrated system robust resource allocation method based on radio frequency stealth. The method comprises the following steps: S1, obtaining a target detection channel frequency response interval Omega rad between a radar communication integrated system and a target and a communication channel frequency response interval Omega com between the radar communication integrated system and a communication user; S2, under the condition that the frequency response of the target detection channel and the frequency response of the communication channel areuncertain, respectively constructing a Cramer-Rao lower bound expression representing the estimation precision of the target time delay parameter and a communication data rate expression representingthe communication service quality; S3, establishing a radar communication integrated system robust resource allocation model based on radio frequency stealth according to the Cramer-Rao lower bound threshold value delta rad and the communication data rate threshold value delta com; and S4, solving the robust resource allocation model of the radar communication integrated system. The radio frequency stealth performance of the system is effectively improved.

Description

technical field [0001] The invention relates to radar communication integration technology, in particular to a robust resource allocation method for a radar communication integration system based on radio frequency stealth. Background technique [0002] With the demand for wireless communication and the rapid increase in the number of wireless sensors on the battlefield, spectrum resources have become one of the scarce and important resources in the informationized battlefield, and the competition for spectrum resources is becoming increasingly severe. It is in this environment that integrated radar communication technology emerged. It can not only make more effective use of increasingly scarce spectrum resources, but also reduce the number of electronic devices and improve information fusion through resource sharing. Orthogonal frequency division multiplexing waveform adopts broadband system, has good data rate and robustness, and its signal array method is easy to estimate...
