Abstract
A wideband radar detection apparatus includes a signal detection section, high rate signal processing section and a low rate signal processing section. The signal detection section sweeps through a range of preselected frequencies and generates an output signal having a pair of single cycle sinusoids for every detected signal. The output signal is provided to the high rate signal processing section and a Sliding Window Discrete Fourier Transform is performed thereon to generate a set of complex values that are related to the fundamental energy content at consecutive points in the sweep. The low rate signal processing section controls sweep parameters and also evaluates the complex values. If the magnitude of the complex values exceed a predefined threshold, then an alert is indicated.
