Title: Proximity-detecting CW radar system
IPC: F42C13/04
Filed: 1985-04-03
Abstract: A proximity-detecting radar system in which the transmitted signal is 0, pi -modulated by a pseudo-random sequence from the generator 8 consisting of a shift register controlled by a clock 9, the signal received after reflection by a target 12 being correlated with a signal corresponding to the modulation sequence but delayed by a time equivalent to that taken for the outward and return path. According to the invention, the period of the signal emitted by the clock 9 is equal to the duration of 1 bit of the pseudo-random sequence from the generator 8 and this clock signal is used to produce a two-phase modulation 10 of the delayed pseudo-random sequence before its correlation with the received signal. This proximity-detecting radar system is intended for use on targets or proximity fuses for intercepting missiles.
