Abstract (en)
[origin: WO2014184760A1] Pulse compression coherent radar provided with a digital generator (1) of pseudo- random waveforms in the form of sequences of first numerical pairs in-phase and quadrature (I, Q); a mass memory (2) adapted to record on it at least a selection of said sequences of first numerical pairs (I, Q) that represent, and permit to generate, analog signals falling in the range of working frequencies of the radar and suitable for transmission by the radar itself; a coherent transceiver comprising a coherent modulator (3), adapted to receive said at least one selection of the sequences of the first numerical pairs (I, Q), read from the mass memory (2), and to generate a respective analog signals; a power amplifier (4) to amplify said analog signals; at least one antenna (6) to transmit said analog signals and receive analog signals reflected from one or more radar target; a coherent demodulator (7) adapted to receive said analog signals reflected and to generate digital signals, representative of said analog signals reflected, in the form of sequences of second numerical pairs (I', Q' ); a frequency synthesizer (8) adapted to generate reference frequencies (fc, fs) used by the coherent modulator (3) and by the coherent demodulator (7); a receiver (9) of the digital correlation type to calculate the mutual correlation function between said selection of sequences of the first numerical pairs (I, Q) and said sequences of second numerical pairs (I', Q'), suitable to detect the radar targets and determine their distance.
