Embodiment

[0034] 1. The launch control computer sends an unlock command to the radar seeker, and the radar seeker enters the search mode after responding to the unlock command.

[0035] 2. When the radar seeker is in the search mode, the control computer on the missile sends the position information of the target to the radar seeker every 10ms (including the missile-to-target distance, azimuth pointing frame angle and pitch pointing frame angle). After the radar seeker receives the target position information, the range gate is set with the range gate centered on the projectile-to-target distance, and the range gate within the range of plus or minus 225m is set. Carry out triangular scanning, the scanning speed is 40° / s, the maximum scanning range is plus or minus 6°, and the maximum scanning period is 0.3s.

[0036] 3. When the radar seeker is in the search mode, it records the position information of each detected target (including the target distance, azimuth frame angle and pitch fr...

Abstract

The invention discloses a radar seeker target selection method, which is used for accurate target selection in complex backgrounds. According to the characteristics of large pitch beam coverage and small distance gate range when the seeker is flying, the present invention realizes the calculation of the relative spatial distance by using the target information provided by the computer on the missile and the target information detected by the radar seeker, so as to achieve The purpose of choosing the target correctly. The invention overcomes the problem that the radar seeker cannot correctly select the target due to inaccurate missile indication information and the interference of ground clutter and foreign objects on the ground. In the radar seeker, it has high engineering value.

Description

technical field [0001] The invention belongs to the field of overall design of a radar seeker, and in particular relates to a method for realizing target selection of a radar seeker. Background technique [0002] The radar seeker has the characteristics of all-day, all-weather and "fire and forget", and has received extensive attention in air-to-surface missiles. Compared with air targets and sea targets, ground targets are more affected by background clutter, and will face interference from ground clutter, ground foreign objects, and various buildings. Therefore, the seeker must have a strong target selection capability. The common target selection methods of existing radar seekers are the distance selection area method and the extended search map selection method. Affected by factors such as measurement errors, the actual trajectory of the missile may have a certain deviation from the ideal trajectory, and the bound target information may also have deviations from the act...
