Fitting Method of Ballistic Curve for Repeating Artillery

Abstract

The invention discloses a ballistic curve fitting method of running-firing cannons and relates to the technical field of the digital computing or data processing equipment or method for specific application. The method comprises: running-firing cannon pills by a radar; optimal starting data searching is carried out on a collected initial speed and thus a point with the highest detection quality is searched and is used as a starting track point; and bidirectional alpha-beta-gamma tracking and filtering are carried out on the starting track point, and with full-ballistic measurement information, tracking and filtering are carried out at previous time and next time by using the starting track point as the center to form a ballistic curve. Compared with the traditional algorithm, the fitting method has the high anti-interference capability; and an accurate ballistic curve can be obtained.

Description

technical field [0001] The invention relates to the technical field of digital calculation or data processing equipment or methods specially suitable for specific applications, and in particular to a ballistic curve fitting method for continuous firing artillery. Background technique [0002] Radar ballistic measurement is an important method of range test, and the use of radar to measure ballistic parameters has become a widely used method. When measuring the muzzle velocity of the continuous firing artillery, the measurement of the muzzle velocity is inaccurate due to the influence of the muzzle flame and the aftereffect period. When using continuous wave radar to measure the initial velocity of projectiles, the (initial velocity) extrapolation technique is often used. Through the processing of the external ballistic measurement data, the radar measurement data is processed with calculations such as track initiation, data association, tracking, filtering, smoothing predic...

AI Technical Summary

Problems solved by technology

The reliability of track initiation is greatly affected by the first frame data

In the measurement of the initial velocity of high-frequency projectiles fired continuously, due to the fact that the initial detection position of the radar is relatively close to the muzzle, the velocity of the projectile is high, and the RCS is small, etc., there will be large interference in the first frame of data, which makes the multi-target tracking effect less effective. Poor, resulting in generally low reliability and stability of ballistic measurement
