  • Pulse compression control system
    Patent number: 5389932
    Abstract: A pulse compression control system uses a code sequence having a larger self correlation side lobe level compared with an ideal code sequence as a transmission code sequence and includes a modulating unit for modulating a pulse by the transmission code sequence in a first order modulation unit. The pulse is received in a demodulating unit where it is demodulated. A reception code sequence from the demodulation unit is modulated by a key code sequence in a second order modulation unit so as to convert it to the ideal code sequence. A self correlation processing unit processes the ideal code sequence for pulse compression.
