Abstract
A radar detector determines whether an input signal is an orthogonally frequency division multiplexed (OFDM) signal or a radar signal by applying at least first and second bandpass filtering operations having substantially non-overlapping passbands to the input signal, each filtering operation having a passband of width substantially less than a relatively large instantaneous bandwidth characteristic of an OFDM signal and substantially greater than a relatively small instantaneous bandwidth characteristic of a radar signal. The detector multiplies power levels of output signals of the first and second filtering operations to form a power product signal and compares the power level of the power product signal with a threshold level and providing an indicating signal in a first state if the power level of the power product signal exceeds the threshold level and otherwise providing said indicating signal in a second state.
