Abstract
A receiver of a frequency-shift-keying, continuous-wave radar comprises at least sampling means taking real samples of the signals in each reception channel and extrapolation means, the extrapolation means producing fictitious samples synchronous with the real samples, the reception signals being formed out of real samples and fictitious samples. Application especially to radars fitted into automobiles.
Claims33
A receiver for a frequency-shift-keying continuous-wave radar transmitting in several frequencies and comprising several corresponding reception channels for receiving signals, wherein said receiver comprises:
- sampling means for taking real samples of the signals in each reception channel;
- and
- extrapolation means for producing fictitious samples synchronous with the real samples,
- wherein reception signals are formed out of the real samples and the fictitious samples.
A method of processing a frequency-shift-keyed continuous-wave signal received in a radar, comprising:
- receiving a return signal in reception channels respectively corresponding to a plurality of transmitted frequencies;
- frequency-shift-keying the return signal;
- sampling real samples of the return signal in each of the reception channels;
- extrapolating the real samples to produce fictitious samples synchronous with the real samples;
- and
- forming reception signals out of said real samples and said fictitious samples.
A receiver for a frequency-shift-keying continuous-wave radar transmitting in several frequencies and including several corresponding reception channels for receiving channels, said receiver comprising:
- a sampling mechanism configured to obtain real samples of the signals in each reception channel;
- and
- an extrapolation mechanism configured to produce fictitious samples synchronous with the real samples,
- wherein reception signals are formed out of the real samples and the fictitious samples.
