Abstract

The invention is characterized in that it includes: the first step, after inputting the ranging data (Range? Data) of the radar signal, the register uses the distance as an indicator to arrange the data positions in the form of unit data; the second step, the sliding window (Sliding? Window) scan The register specifies at least one or more detection units (Test? Cell) and specifies at least one or more reference cells (Reference? Cell); in the third step, the comparator compares the data values ​​of the detection unit and the reference unit respectively. ; and the fourth step, based on the comparison result of the comparator, determine the detection unit with a larger data value than the reference unit as target data, and treat the detection unit with a smaller data value than the reference unit as noise.

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...
