Embodiment Construction

[0050] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] Starting from the requirements of today's military applications, the present invention proposes a joint optimization method of dwell time and radiation power of networked radars for low interception, with the target tracking accuracy meeting the preset target tracking error threshold and the radiation resources of the networked radar system as constraints Conditions, with the optimization goal of minimizing the weighted sum of dwell time resources and radiation power resources of each radar irradiation target at each moment, a joint optimization model of dwell time and radiation power of networked radars oriented to low interception is established, thereby reducing the cost of networked radars. The system's radio frequency radiation resource consumption effectively improves its low interception performance.

Abstract

The invention discloses a networking radar residence time and radiation power joint optimization method for low interception. The method comprises the following steps: S1, determining a networking radar system architecture and a task thereof; s2, taking the residence time and the radiation power of each radar as independent variables, constructing a prediction Bayesian Schramer lower bound matrixof the target state estimation error, and taking the trace of the prediction Bayesian Schramer lower bound matrix as a measurement index of the target tracking precision; s3, taking the weighted sum Fk of residence time resources and radiation power resources of each radar irradiation target at the moment k as an optimization target function; s4, establishing a networking radar residence time andradiation power joint optimization model for low interception; and S5, solving the networking radar residence time and radiation power joint optimization model for low interception by using an interior point method. According to the invention, the radio frequency radiation resource consumption of the networking radar system is reduced, and the low interception performance of the networking radar system is effectively improved.

Description

technical field [0001] The invention relates to radar signal processing technology, in particular to a joint optimization method of dwell time and radiation power of networked radar for low interception. Background technique [0002] In recent years, networked radar systems such as multistatic radar and multiple-input multiple-output radar have attracted widespread attention in the academic community. Compared with the traditional monostatic radar system, the networked radar system has many potential advantages, such as superior waveform diversity gain, space diversity gain and better target detection and tracking performance. [0003] For the resource allocation problem of networked radar system under target tracking, domestic and foreign scholars have proposed a series of resource allocation management methods, the purpose is to fully utilize the system potential and improve system performance. According to the optimization objective, these methods can be divided into two...
