Radar detection method and apparatus
First Claim
1. A method for detecting an object with a radar system comprising:
- generating a detection table containing a plurality of indicators, each indicative of the presence or absence of the object;
combining at least two of the plurality of indicators contained in the detection table; and
providing an object detection message if at least one of the combined indicators is indicative of the presence of the object.

Abstract
A radar detection process includes computing a derivative of an FFT output signal to detect an object within a specified detection zone. In one embodiment, a zero crossing in the second derivative of the FFT output signal indicates the presence of an object. The range of the object is determined as a function of the frequency at which the zero crossing occurs. Also described is a detection table containing indicators of the presence or absence of an object within a respective radar beam and processing cycle. At least two such indicators are combined in order to detect the presence of an object within the detection zone.
