A Track Initiation Algorithm Based on UAV Surveillance Radar

Abstract

The invention discloses a flight path starting algorithm based on an unmanned aerial vehicle surveillance radar. The flight path starting algorithm comprises the following steps that single side multiple hypothesis correlation judgment is carried out on radar scanned points by the system to form a temporary flight path with single side multiple hypothesis; the temporary flight path with the singleside multiple hypothesis is subjected to multi-model temporary flight path starting judgement to form a temporary flight path satisfying flight path starting conditions; and the temporary flight pathsatisfying the flight path starting conditions is subjected to flight path filtering judgment to form a stable flight path. The problems that the unmanned aerial vehicle tarting flight path is difficult and false alarm in the clutter area is serious are solved. Unmanned aerial vehicle surveillance efficiency is improved.

Description

technical field [0001] The invention relates to the field of three-coordinate active phased array radar low-altitude surveillance, in particular to a track initiation algorithm based on the UAV surveillance radar. Background technique [0002] In recent years, with the rapid development of drone technology, drones have expanded from the original military market to the civilian market on a large scale. Safety accidents caused by black flights are common, which poses a huge threat to my country's low-altitude field control. Under the urgent needs of national security and defense departments such as border defense, civil air defense, and public security, UAV surveillance radars have gradually emerged. [0003] Since civilian drones usually use non-metallic fuselage and the fuselage is small, the RCS reflection cross-sectional area is small, and the radar detection echo is weak, especially the characteristics of slow flight speed, low flying height, and flexible flight. Detecti...
