Continuous wave one-dimensional phase sweep off-target amount vector detection method and device

Abstract

The invention discloses a continuous wave one-dimensional phase scanning miss distance vector detection method and device. The method comprises the following steps: continuously scanning a target region at high speed in the horizontal direction by adopting a one-dimensional phase scanning mechanism, fixing and setting the beam direction of each beam position of a radar in advance, and sequentially and cyclically scanning each beam position from left to right from the first beam position on left; when the radar scans a certain beam position, measuring an object distance through a linearly frequency-modulated continuous wave distance measurement mechanism by virtue of the radar, transmitting a frequency-modulated continuous wave signal to a scanning sector, and when an object enters a detection area, performing miss distance vector measurement on the distance Rp' and direction of the object relative to the radar in broadband linearly frequency-modulated continuous wave distance measurement and single pulse sum and difference angle measurement manners, and converting the distance and direction of the object relative to the radar into a miss distance vector relative to a target by utilizing a geometrical relationship of the distance and the azimuth angle relative to the target and a coordinate conversion formula by virtue of a radar data processing extension.

Description

Technical field [0001] The invention relates to a continuous wave one-dimensional phase sweep miss target vector detection method and device. Background technique [0002] With the continuous development of miss-measuring technology, the current working mode of miss-measuring systems has gradually developed from a collaborative type to a non-cooperative type; the measurement data type is based on the mature scalar miss-measuring measurement, and is based on the vector miss-measuring Develop and continuously improve. The so-called scalar miss measurement refers to the measurement of the minimum relative distance between the projectile and the target during the encounter, and the vector miss measurement requires not only the scalar miss, but also the relative position (distance, angle) of the encounter between the projectile and the target. And relative speed. [0003] Missing distance measurement can use radio waves, light waves, sound waves and other energy forms as a medium to o...

Problems solved by technology

This method has the following disadvantages: good lighting conditions are required, and it is greatly affected by meteorological conditions; data will be lost when the target is hit; the time of film recording is limited and the stability of the camera; in addition, its data processing is relatively complicated

However, the current target measurement device cannot perform reliable vector detection on multiple high-speed small targets; in addition, since the miss-target measurement device is usually placed near the target, the probability of being hit is high, it is easy to be damaged and cannot be used repeatedly
