Body target trigger point design method for fixed-angle fuze actuation

Abstract

The invention discloses a body target trigger point design method for fixed-angle fuze actuation, which comprises the steps of first, constructing a body target three-dimensional model by adopting a 3D model building tool; second, exporting the model to be an stl-format file; third, extracting vertex coordinates of a body target triangle surface element in the stl file, and forming a vertex coordinate file of the body target triangular surface element; fourth, calculating a fuze actuation point by adopting a fuze trigger line calculation model so as to realize a body target trigger point design method for fixed-angle fuze actuation. According to the invention, the body target trigger point model is constructed, and trigger points are distributed all over the target body, thereby being welldrawing the outline of the target. Compared with the traditional trigger point model, the number of the trigger points increases hundreds of times. The fuze trigger line can start to accumulate starting energy when touching any trigger point on the body target, thereby solving a problem of inaccurate fuze actuation position due to a very small number of traditional trigger points.

Description

technical field [0001] The invention relates to the fields of instrumentation analysis and measurement control. More specifically, it relates to a method for designing a body target trigger point for fixed-angle fuze activation. Background technique [0002] In the coordination design of anti-aircraft missiles, the start-up characteristic simulation of radio or optical beam fixed-angle fuzes mostly adopts the "fuze trigger line method". It can also reflect certain fuze activation rules. The fuze trigger line method involves "fuze trigger line model" and "target trigger point model". A "fuze trigger line model" is an assumed curve of angle versus distance with respect to the fuze antenna pattern or optical field of view. For fixed-angle fuzes, when components with a certain scattering area on the target body, such as the fuselage head, tail, wing or empennage end, touch the trigger line, the fuze starts to react and accumulate signals. Delay just sends the signal that det...
