Patent ID: 7932852

Claim:
A radar unit, comprising: an antenna; an arbitrary waveform generator to issue an arbitrary radar waveform signal at a given pulse repetition frequency, the arbitrary waveform generator being adapted to adjust the phase of the radar waveform signal as a function of a phase adjustment signal; a transmit amplifier coupled to the antenna; a receive unit coupled to the antenna to receive multiple radar pulses to retrieve a Doppler spectrum; a 2D filter for generating associate values of radar response and coordinate data; a noise predictor coupled to the receiver to receive at least one prevalent radio frequency interference; a demodulation and decoding bank comprising known information on the modulation and coding principle of the prevalent radio frequency interference signal, the radio frequency interference signal typically operating according to a predetermined refresh frequency at which redundant information is repeated; said noise predictor operative to receive, demodulate and decode the information content of the at least one radio frequency interference signal, wherein: the arbitrary wave generator is adapted to generate pulse-compressed chirps, and wherein the arbitrary wave generator is synchronized with the at least one prevalent radio frequency interference signal, whereby, the arbitrary wave generator is controlled to produce an overall radar pulse composed of at least a first segment and a second segment whose time/frequency rates may differ from one another, whereby the overall radar pulses vary from pulse to pulse such that for the coinciding frequency of the at least one prevalent radio frequency interference signal, the time between radar pulses is an integer divisor of the periodicity of the at least one prevalent radio frequency interference signal.
