Abstract

The present invention relates to an encoding frequency-hopping high-resolution distance-measuring speed-measuring method and radar. In particular, it is applicable to automobile anti-collision radar and police speed-measuring radar, and can be substituted for infrared alarm to make all-weather real-time safety supervisory control for large-range sensitive area. Said invention also provides the concrete steps of said distance-measuring and speed-measuring method, and can make several radars have strong anti-interference power when they are simultaneously worked.

Description

technical field

[0001] The invention belongs to the field of radar technology, and relates to a radar and its distance measurement and speed measurement method, in particular to a coded frequency hopping high-resolution distance measurement and speed measurement method and a radar, which can be used for high-resolution and real-time detection of single or multiple radars at the same time. Measure the distance and speed of multiple targets within the observation area. Background technique

[0002] In order to use radar to measure the distance and speed of multiple objects at the same time with high resolution, the following methods are commonly used at present

[0003] (1) Use the triangular linear frequency-modulated continuous wave (FMCW) method [the principle of radar, edited by Ding Lufei and Geng Fulu in the third edition of Xidian University Press]. This approach requires the use of a broadband voltage-controlled oscillator (VCO) and a high sampling rate analog-to-digi...
