摘要：A radar detection process includes computing a derivative of an FFT outputsignal 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 anobject. The range of the object is determined as a function of the frequency at which thezero crossing occurs. Also described is a detection table containing indicators of thepresence or absence of an object within a respective radar beam and processing cycle. Atleast two such indicators are combined in order to detect the presence of an objectwithin the detection zone and with changing range gates in each of the antenna beamsthe coverage of the detection zone can be varied.
