CONTINUOUS WAVE DOPPLER RADAR AND PSEUDO-RANDOM CODING FOR ANGLE AND DISTANCE MEASUREMENT

摘要

The invention relates to a continuous wave doppler and PSEUDO-RANDOM CODING for ANGLE AND DISTANCE MEASUREMENT. This radar comprises a 904 transmit antenna fed by a signal supplied by a signal generator. CONTINUOUS WAVE TRANSMITTER 901 PHASE MODULE BY A PSEUDO-RANDOM CODE GENERATOR 910. THE SIGNALS ARE RECEIVED BY A NETWORK ANTENNA WITH SWITCHED ELEMENTS 913, 913, WHICH IS CONNECTED TO 2N1 RECEIVER CHANNELS CORRESPONDING TO ALL RECEPTION ANGLES. THESE CHANNELS EACH INCLUDE A 912 MIXER RECEIVING LOCAL OSCILLATOR FREQUENCY 908, A CORRELATION DETECTOR 914, 915 PROVIDING DISTANCE AND A DOPPLER 927, 928 FILTER BENCH BY REMOTE TRANCHE. / P P THE INVENTION APPLIES TO DOPPLER RADARS PROVIDING ANGLE, DISTANCE AND SPEED. / P
