Abstract: Radar proximity fuse (1) adapted to receive an echo radar signal (s_rx) produced by the reflection on a target (T) of a transmitted radar signal (s_tx), the transmitted signal (s_tx) comprising a sequence of M impulses coded with a phase code (p_cd). The radar proximity fuse (1) comprising: a radiofrequency analog receiving front end (15) for receiving the echo radar signal (s_rx), adapted to provide in output a baseband signal starting from the echo radar signal (s_rx) received; an analog to digital converter (12) positioned at the output of the analog receiving front end (15) adapted to sample the baseband signal to obtain in output a sequence of digital samples (d_rx); a digital processing block (20) comprising a plurality of digital processing channels (C1, C2, . . . CN) each associated to a respective range gate and each adapted to receive in input said sequence of digital samples (d_rx).
