Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044]The working mode of the radar processor of the present invention is divided into two types: active and passive. The working principle of the active radar processor is to search for the reflected echo of the received target after transmitting a signal, and locate the target, and can work all-weather or quasi-all-weather. It has a long range and can attack in all directions, but there are problems such as angular flicker interference, and it is easy to be detected by the enemy and implement electronic interference. The working principle of the passive radar processor is to use the radiation energy of the target as the signal source to realize the target positioning. The detection method is concealed and the anti-interference is strong, but its detection has no distance information and is greatly affected by the stealth performance of the t...

Abstract

The invention provides an active and passive radar composite seeker processor system based on a VPX architecture. The signal processor comprises a processor backboard, an interface timing sequence unit, an active acquisition and emission unit, a passive acquisition and processing unit, a radar signal processing unit and a radar image processing unit, and each unit performs data interaction with other units in the signal processor through SRIO, RS485, GPIO and other interfaces. Different cells are combined, and three working modes, namely active radar SAR imaging, active radar monopulse and passive radar work modes, can be independently adopted; and the functions of large forward inclination SAR imaging, SAR image matching and positioning in an active radar SAR imaging mode, target detection, distance measurement, angle measurement and tracking in an active radar monopulse model, target searching and direction finding in a passive radar mode and the like are realized. The system meets the integrated requirements of the three work modes, and the radar signal processing unit can be used for receiving a control instruction to complete switching among the modes.

Description

technical field [0001] The invention relates to an active and passive radar composite seeker processor system based on a VPX architecture, which is suitable for radar-related weaponry products, and relates to a radar seeker data acquisition and processing scheme based on the VPX architecture. Background technique [0002] The radar seeker active radar and passive radar are complementary in performance, which can improve the performance of the weapon system. At present, the radar functional modules on the missile-borne platform are independent of each other, and the integrated design of active radar and passive radar has not been realized. Therefore, it is necessary to realize the high-speed interconnection of each module and realize the integrated design of different working modes. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, the present invention proposes an active and passive radar c...
