Problems solved by technology

[0004] However, although the existing research results involve the optimization of radiation parameters in the target tracking of networked radar systems, under the condition of ensuring the given target tracking performance, the parameters such as radar sampling interval, dwell time, and radiation power are jointly optimized. To a certain extent, the radio frequency stealth performance in the networked radar target tracking process has been improved, but the existing research results are only for single target tracking scenarios, and scientific and reasonable radio frequency stealth indicators have not been used to evaluate the radio frequency stealth of the networked radar system. performance is measured, with some limitations
There is no public report on the research on the radiation parameter control method of networked radar system for multi-target tracking

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0036] The present invention considers a networked radar system composed of a shared radar transmitter and multiple radar receivers. At each moment of tracking, the shared radar transmitter emits signals to irradiate multiple targets, and each receiver receives signals reflected by multiple targets. The radar signal is used to track each target. Firstly, according to the radar cross-section RCS database of each target obtained in advance through electromagnetic simulation calculation and the target tracking process, the RCS of each target relative to different radar transmitter-receiver pairs and the distance of the target relative to the radar transmitter and each receiver are obtained; second...

Abstract

The invention discloses a radiation parameter control method for a networked radar system under multi-target tracking. According to the method, a networked radar system formed by a shared radar transmitter and a plurality of radar receivers adjusts radiation parameters like a sampling interval, residence time, and a radiation power of the shared radar transmitter during the multi-target tracking process adaptively and dynamically under the circumstance that preset conditions of all target tracking precision values, detection performances, and the transmitting resource constraint of the networked radar system are met and thus the interception probability of the networked radar system is minimized, so that the radio-frequency stealth performance of the networked radar system in multi-targettracking is improved.

Description

technical field [0001] The invention relates to a radiation parameter control method under multi-target tracking of a networked radar system, belonging to the technical field of radar signal processing. Background technique [0002] The increasingly complex battlefield environment poses severe challenges to modern radar detection systems. In future information warfare, the simple combination and superposition of a single radar or multiple radars can no longer meet the needs of joint operations. Therefore, the networked radar system is the development trend of the future tactical system confrontation. It can improve the situational awareness of the weapon platform, form a combat advantage in the complex electromagnetic spectrum environment of the battlefield, and improve the networked combat capability of our army's radar detection system. [0003] With the development of advanced materials and electronic technology, various advanced enemy passive detection systems and passi...
