Embodiment Construction

[0016] The following combination Figure 1-2 Specific embodiments of the present invention are described in detail.

[0017] The present invention proposes a method for channel compression of multi-branch fuze detection range under ultra-low altitude combat conditions:

[0018] The first step is to calculate the position and attitude information of the missile and the ground / sea surface according to the detection information of the fuze height branch and the attitude information of the projectile body.

[0019] According to the detection information of the fuze height branch, the height H between the fuze and the ground / sea surface can be obtained; the yaw angle ψ of the projectile can be obtained according to the inertial navigation measurement information m is, pitch angle θ m , roll angle γ m , to get the transformation matrix M from the projectile coordinate system to the ground coordinate system M→G .

[0020] The second step is to calculate the angle between the fuz...

Abstract

The invention discloses a method for compressing a multi-branch fuse detection distance channel under an ultra-low-altitude combat condition. The method comprises calculating a distance compression range of a target detection branch in real time through comprehensive utilization of posture information of a projectile body, height branch detection information of a fuse and an antenna direction diagram of a target detection branch. Compared with a previous fuse detection calculation method, the method can achieve optimization of design based on full utilization of existing detection information,without increasing other hardware detection device or complexity of system hardware design. While avoiding early explosion caused by sea surface echo signals detected by the fuse, the method exerts detection capability of the fuse on a target to a maximum extent, thereby realizing effective detection and killing of the target.

Description

technical field [0001] The invention relates to the technical field of fuze detection, in particular to a multi-branch fuze detection range channel compression method under ultra-low altitude combat conditions. Background technique [0002] During the projectile-target encounter, due to the drastic change of the projectile attitude, the target detection channel of the multi-branch fuze may detect the ground / sea surface echo. In the previous methods, the detection range of the target branch of the fuze is not compressed or is consistent with the compressed range of the distance of the altitude branch, which leads to the early explosion of the sea echo detected by the target branch of the fuze; The target is detected, causing the missile to be unable to effectively kill the target. Contents of the invention [0003] The purpose of the present invention is to provide a method for compressing the detection distance channels of multi-branch fuzes under ultra-low altitude comba...
