Abstract

The present invention is characterized in a method comprises a first step of arranging data positions as cell data forms by using distances as indexes by a register after inputting Range Data of a radar signal; a second step of scanning the register by a Sliding Window, assigning at least more than one Test Cell, and assigning at least more than one Reference Cell; a third step of respectively comparing data values of the Test Cells and data values of the Reference Cells by a comparator; and a fourth step of processing the Test Cells having the data values smaller than that of the Reference Cells as noises, according comparative results of the comparator, by determining the Test Cells having the data values larger than that of the Reference Cells as target data.

Description

technical field [0001] The present invention relates to a method for increasing the target detection probability of radar signals, and more specifically, relates to a method that can minimize the target misdetection of short-distance targets in the CFAR (Constant FalseAlamRate, Constant False Alarm Rate) of radar devices. , a method of increasing the probability of target detection of a radar signal by increasing the probability of detection. Background technique [0002] Generally speaking, CFAR (ConstantFalseAlamRate) applied to radar is used as a method to determine the threshold (Threshold) of the received signal, comparing the surrounding distance (ReferenceCell, reference unit) and the signal used to judge whether there is a target (TestCell, detection unit) According to the comparison result, it is distinguished whether the received signal is noise or target signal. [0003] On the other hand, the radar sends radio waves, and the received signal includes not only the...
