Embodiment Construction

[0065] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] Starting from the actual military application requirements, the present invention proposes a low intercept-oriented distributed MIMO radar communication integrated system power allocation method, which reduces the radio frequency radiation resource consumption of the distributed MIMO radar communication integrated system, and effectively improves the distributed MIMO radar. Low intercept performance for integrated communication systems. First, consider a distributed MIMO integrated radar communication system consisting of multiple integrated radar communication transmitters, multiple radar receivers and multiple communication receivers, where the integrated radar communication transmitter can simultaneously transmit multiple independent The beam completes the functions of target positioning and data communication. Then, the target mot...

Abstract

The invention discloses a distributed MIMO radar communication integrated system power distribution method for low interception. The method comprises the following steps: S1, determining the composition and function of a distributed MIMO radar communication integrated system; S2, adopting a target motion parameter estimation Cramer-Rao lower bound matrix to represent the target positioning precision of the distributed MIMO radar communication integrated system, and adopting channel capacity to represent the data communication performance of the distributed MIMO radar communication integrated system; S3, establishing a distributed MIMO radar communication integrated system power distribution model for low interception; and S4, solving the distributed MIMO radar communication integrated system power distribution model for low interception by adopting positive semidefinite programming and a Lagrange multiplier method respectively. According to the method, the radio frequency radiation resource consumption of the distributed MIMO radar communication integrated system is reduced, and the low interception performance of the distributed MIMO radar communication integrated system is effectively improved.

Description

technical field [0001] The invention relates to radar signal processing technology, in particular to a low intercept-oriented distributed MIMO radar communication integrated system power distribution method. Background technique [0002] In order to improve the survivability and combat effectiveness of modern battlefield weapons and equipment, especially mobile platforms, such as fighter jets, warships, aircraft carriers, armored vehicles, etc., more and more radio frequency sensors have to be equipped at the same time. However, the continuous increase in the number of sensors not only consumes a lot of radio frequency resources and occupies more space, but also seriously weakens the maneuverability of the combat platform, increases the radar cross-section, and reduces the anti-jamming ability and Combat effectiveness of modern weapons and equipment. [0003] Distributed Multiple-Input Multiple-Output (MIMO) radar communication integrated system utilizes broadband phased ar...
