Embodiment Construction

[0046] The present invention will be further explained below in conjunction with the accompanying drawings.

[0047] Such as figure 2As shown, the radio frequency stealth radar networking power allocation method based on cooperative game of the present invention comprises the following steps:

[0048] Step 1. Determine channel propagation loss and target RCS

[0049] According to the prior knowledge such as the propagation loss between each radar and the target and the RCS of the target relative to each radar, the propagation loss between each radar and the target and the RCS of the target relative to each radar are determined. It is assumed that the radar networking system model working in the same frequency band is as follows figure 1 shown

[0050] The channel propagation loss between each radar and the target in the radar networking system is mathematically described as:

[0051]

[0052] in, is the transmitting antenna gain of the i-th radar, is the receiving ...

Abstract

The invention discloses a radio frequency stealth radar networking power distribution method based on a cooperative game. The method comprises steps of firstly acquiring propagation loss between each radar and a target and the RCS of the target relative to each radar according to prior knowledge in the case that each radar works in the same frequency band in a radar networking system; then, taking the maximization of total emission power of the radar networking network as an objective, establishing a radio frequency stealth radar networking power distribution model based on a cooperative game under the condition that the target detection performance is met, and solving the model through the classic Lagrange relaxation algorithm; through iteration calculation, selecting each radar emission power, defined in the description, allowing the total emission power of the radar networking system to be the smallest to be the optimal solution under the condition that the target detection performance is met, and substituting the emission power, defined in the description, of each radar into the distribution model so as to obtain the smallest total emission power, which meets the constraint condition, of the radar networking system. According to the invention, the total emission power of each radar in the system is reduced ad the radio frequency stealth performance of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of radar power distribution, and in particular relates to a cooperative game-based radio frequency stealth radar networking power distribution method. Background technique [0002] Judging from the development trend of weapons and equipment, system confrontation is a characteristic of modern high-tech warfare. From the perspective of network development law, the integration of radar networking system and multi-radar system is the inevitable development of the times. Relying on the highly developed network information technology, the networked battlefield system is the basic form of future warfare. The direction of future change is to transform "sensor-centric warfare" into "network-centric warfare", relying on networked battlefield systems, Provide commanders with real-time and transparent space awareness through radar networking system information fusion. The radar networking system refers to the connecti...
