Embodiment Construction

[0049]The technical scheme adopted in the present invention is based on networking radar, using Kalman filter and multi-objective PSO algorithm, while effectively optimizing the radar site configuration, it can adaptively terminate the optimization calculation process according to the optimization result, including the following steps:

[0050] For the first three moments, they are regarded as independent of each other, and the optimal site configuration scheme is calculated using the traditional PSO method. Then you can enter the algorithm proposed in this paper:

[0051] S1. Using the prediction model of Kalman filter, according to the previous site optimization configuration plan, predict the approximate site optimization configuration plan at the next moment. The specific operation method is as follows:

[0052] The state vector of the site configuration scheme at the third moment is:

[0053]

[0054] in and are the antenna positions of the optimal site configurat...

Abstract

The invention discloses a method for configuring antennas on the basis of predicted networking radar in dynamic environments, belongs to the technical field of radar, and particularly relates to optimal configuration on networking radar sites by the aid of particle swarm optimization algorithms on the basis of state prediction in dynamic environments. The method has the advantages that the approximate locations of radar sites at new moments can be predicted according to optimal site configuration schemes at a previous moment in dynamic battlefield environments, then actual optimal site configuration schemes can be solved by the aid of PSO (particle swarm optimization) processes, accordingly, the computing time can be effectively shortened, wastage of computing resources can be prevented, and optimal configuration results of the radar sites at various moments in the dynamic environments can be quickly obtained.

Description

technical field [0001] The invention belongs to the field of radar technology, and in particular relates to optimizing the configuration of networked radar sites by using a particle swarm optimization algorithm based on state prediction in a dynamic environment. Background technique [0002] With the development of integrated electronic warfare, traditional radars working alone cannot complete multiple tasks, and their own survival has become an urgent problem to be solved, and a single radar cannot compete with electronic countermeasures systems. In this case, the multi-function radar network emerges as the times require. Relevant experts of the U.S. Air Force and Army generally believe that networking is the most promising anti-stealth and anti-jamming approach. The U.S. Army has concentrated its efforts on prioritizing the networking work to improve its surveillance and combat capabilities, and has studied the continuous improvement and perfection of the mature intellige...
