<p>A continuous wave frequency shift-keyed radar apparatus comprising means for changing the frequency of the transmitted continuous wave periodically and in a pseudo-random sequence, means for mixing the received wave with the transmitted wave or a delayed version thereof to produce a beat signal, means for sampling the beat signal, in respect of each period of simultaneous transmission and reception at the same frequency, means for reordering successive segments of the sampled beat signal to put them in sequential frequency order, and means for transforming the reordered segments to provide an output signal in the range domain.</p> |
