Moving target track acquisition method based on multi-observation-post digital telescope

Abstract

The invention provides a moving target track acquisition method based on a multi-observation-post digital telescope, and solves the positioning problem of a low-altitude ultra-low-altitude short-rangemaneuvering target so as to compensate for a low-altitude radar detection blind area. Aiming at the problems that the air condition of an observation-post digital telescope are influenced by a plurality of factors, the information precision is low and the high discreteness is big in the prior art, the invention starts from the angle of multi-source air condition information fusion, and the methodcomprises the steps: establishing a target motion law mathematical model, and on the basis, estimating the target distance information by using an estimated value instead of observation data and adopting a least square cross positioning algorithm, and obtaining a target track. The method is suitable for a ground observation post air situation system, shows the battlefield situation, and providestarget indication for a ground radar.

Description

Technical field [0001] The invention relates to a moving target track acquisition method based on a multi-observation post digital telescope, which belongs to the field of low-altitude target detection, solves the positioning problem of low-altitude or ultra-low-altitude short-range maneuvering targets, compensates for low-altitude radar detection blind areas, and is suitable for ground observation post air situation systems , And provide target indication for ground radar. Background technique [0002] Low-altitude target detection is dominated by sophisticated high-end products such as low-altitude radar and photoelectric composite detection equipment. Such products are expensive, complicated in technology, and restricted in use and promotion. Due to the limitations of electromagnetic interference, earth curvature and complex terrain, ground-based radars have a short detection range for low-altitude targets, and the firepower unit cannot effectively respond to air targets in a...

Problems solved by technology

[0004] In order to solve the problem that the original data collected by the observation post digital telescope has low accuracy, large jitter, non-stationary, and lack of target distance information, compared with radar air conditions, the original data collected by the observation post digital telescope cannot directly obtain the target track.
