Problems solved by technology

The positioning accuracy of the interferometer is directly related to the lateral distance of the helicopter relative to the target flight, which has strict requirements on the heading of the helicopter, which increases the risk of helicopter exposure, and its final positioning result is not enough to guide the fire control system to strike

Embodiment Construction

[0018] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0019] The radar ground static air defense unit detection method based on interferometer information fusion adopted by the present invention comprises the following steps:

[0020] (1) Obtain the orientation information of the air defense unit within the current range through the interferometer;

[0021] (2) Obtain all target azimuth and distance information within the radar search range through radar track processing;

[0022] (3) Fusion of interferometer information and radar information to determine the target area;

[0023] (4) Multi-frame data association to determine the target position;

[0024] in:

[0025] Step (1) involves the time-domain detection of the echo signal of the air defense unit, signal pre-sorting, classification and buffering, pulse train analysis (comparison with the existing radar library according to the PRF and pulse group structure...

Abstract

The invention relates to a radar ground static air defense unit detection method based on interferometer information fusing. When a helicopter flies, the orientation and distance of the target relative to a radar change in real time, and since an air defense unit is static, the intersecting point of different rays drawn according to orientation angles measured by an interferometer in real time isthe position of the air defense unit, and the air defense unit can be completely determined after position information and radar flight paths are matched. The radar ground static air defense unit detection method is suitable for being applied to detection of the static air defense unit through the helicopter-mounted radar.

Description

technical field [0001] The invention belongs to the field of radar target detection and target identification, and in particular relates to a detection method for radar ground stationary air defense units based on interferometer information fusion. Background technique [0002] In modern warfare, armed helicopters have become the most effective weapon to support ground forces in operations and seize ultra-low-altitude air supremacy and sea supremacy, and equipped with advanced airborne radar can greatly improve its combat power and combat effectiveness. From the perspective of combat mode and tactics, the helicopter is required to fly close to the ground, covertly engage the enemy, and maneuver to evade immediately after a sudden attack. By flying close to the ground at an ultra-low altitude, the helicopter can bypass the search of the enemy's air defense radar, realize the reconnaissance of the enemy's deep area, and can also destroy the enemy's air defense unit and seize a...
