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...
