Embodiment Construction

[0041] The patent will be further described below in conjunction with the accompanying drawings and specific examples, but not as a limitation of the patent.

[0042] 1. Determine the propagation loss of each channel and the RCS of the target relative to each radar:

[0043] The invention proposes a radar networking power control method based on non-cooperative game under spectrum sharing. It utilizes prior knowledge such as the propagation loss between each radar and the target, between each radar and the communication system, and the RCS of the target relative to each radar. Assuming that the radar networking and communication system models working in the same frequency band are as follows: figure 1 shown. Therefore, parameters such as the propagation loss between each radar and the target, between each radar and the communication system, and the RCS of the target relative to each radar should be determined first. The channel propagation losses between each radar and the ta...

Abstract

The invention discloses a radar network power control method based on a non-cooperative game under spectrum sharing. The method comprises the steps of under the condition that a radar network system and a communication system work in a same frequency band, acquiring propagation losses between each radar and a target and each radar and the communication system and a RCS of the target with respect to each radar in the networking system according to priori knowledge; and then using minimization of transmitting power of each radar in the radar network system as a target, under the condition of meeting certain target detection performance and the maximum acceptable interference power threshold of the communication system, building a radar network power control model based on the non-cooperativegame under spectrum sharing, and solving the model via a distributed power iteration algorithm. According to the control method, the transmission power of each radar in the radar network system is reduced, and the spectrum sharing performance between the radar network and the communication system is enhanced.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, and specifically proposes a radar networking power control method based on non-cooperative game under spectrum sharing. Background technique [0002] When the radars in the radar networking system work in the same frequency band, it is often necessary to control the transmission power of each radar. There are two main purposes: one is to reduce the mutual interference between the radars and improve the radio frequency stealth performance of the system The second is to reduce the interference of each radar in the radar networking system to the communication system working in the same frequency band. In this way, not only can more available spectrum resources be developed, but also the utilization rate of available spectrum resources can be effectively improved. [0003] Radar networking systems usually use distributed power control technology to expand the working range of each ra...
