Embodiment Construction

[0056] The structure and working process of the present invention will be further described below in conjunction with the accompanying drawings.

[0057] The present invention firstly considers a networked radar system composed of N radars in a two-dimensional space to track multiple moving targets dispersedly deployed in space; secondly, derives the Bayesian Kramer- The Bayesian Cramér-Rao Lower Bound (BCRLB) expression; on this basis, with the constraints of the networked radar radiation resources and the tolerable interference energy in the communication area, and the optimization goal of minimizing the trace of the BCRLB matrix, a group is established. Networked radar power time joint optimization allocation model, adaptive dynamic optimization of node selection and radiation resource allocation during multi-target tracking of networked radar, in order to achieve the purpose of improving multi-target tracking performance.

[0058] Based on the actual combat scenario, the p...

Abstract

The invention discloses a networking radar power and time joint optimization method for multi-target tracking under space-frequency sensing, and the method comprises the steps: S1, building a state equation of a moving target, a radar observation model, and an interference model for a multi-target tracking scene of a networking radar system; s2, deriving a Bayesian Cramer-Rao lower bound (BCRLB) matrix expression which represents the multi-target tracking precision; s3, establishing a networking radar power time joint optimization distribution model for multi-target tracking under space-frequency sensing by taking a networking radar radiation resource and a communication area tolerable interference energy upper limit as constraint conditions and taking a trace of a minimum BCRLB matrix as an optimization target; and S4, solving the joint optimization distribution model by adopting an interior point method and a cyclic minimum method. According to the method, adaptive dynamic optimization can be carried out on node selection and radiation resource allocation during networking radar multi-target tracking, so that the multi-target tracking performance of the networking radar is improved.

Description

technical field [0001] The invention relates to a radar resource allocation technology, in particular to a multi-target tracking-oriented networked radar power-time joint optimization method under space-frequency perception. Background technique [0002] With the rapid increase of radio frequency equipment in the modern battlefield and the widening of the working spectrum, the traditional methods used to solve the radio frequency spectrum congestion of radar and wireless communication systems have become more and more difficult to meet the actual needs. How to make radar systems work in harmony with other overlapping spectrum communication systems has become a hot topic. For this type of problem, it is necessary to consider how to effectively improve the spectrum utilization, and how to effectively calculate and reduce the mutual interference between the radar system and the communication system when the radar system and the communication system share the same frequency spec...
