Continuous wave one-dimensional phase scanning target-missing quality vector detection method and device thereof

Abstract

The invention provides a continuous wave one-dimensional phase scanning target-missing quality vector detection method and a device thereof, a one-dimensional phase scanning system is adopted to carry out high-speed continuous scanning to a target section in a horizontal direction, the beam pointing of each beam position of a radar is fixed and set in advance, and then scan round is sequentially carried out on each beam position from left to right; when the radar carries out scanning to a certain beam position, the radar adopts a linear frequency modulation continuous wave distance measurement system to measure the distance of targets, and transmits frequency modulation continuous wave signals to a scan sector, when a target enters a detection zone, broadband linear frequency modulation continuous wave distance measurement and single pulse sum and difference angle measurement manners are adopted to carry out vector target-missing quality measurement to the target relative to the distance R' and position of the radar, then a radar data processing extension set utilizes the geometrical relationship and coordinate conversion formula relative to the distance of the targets and the angle of the position to calculate the distance and position of the target relative to the radar into the vector target-missing quality relative to the target.

Description

technical field [0001] The invention relates to a continuous wave one-dimensional phase sweep off-target amount vector detection method and device. Background technique [0002] With the continuous development of the off-target measurement technology, the current working method of the off-target measurement system has gradually developed from the collaborative type to the non-cooperative type; the measurement data type is based on the mature scalar type off-target measurement, and is moving to the vector off-target measurement. 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 process, while the vector miss measurement not only needs to obtain the scalar miss quantity, but also measures the relative position (distance, angle) of the projectile and the target encounter process. and relative speed. [0003] The measurement of the amount ...

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
