AMBIGUE DISTANCE MEASUREMENT METHOD AND PULSE DOPPLER RADAR USING SUCH A METHOD

摘要

The present invention relates to a method for measuring the AMBIGUE DISTANCE IN A DOPPLER RADAR WITH REPEAT FREQUENCY PULSES F / P P THE DEVICE INCLUDES MEANS OF TRANSPOSITION 3 OF THE SIGNAL RECEIVED R (T) BY A FREQUENCY SIGNAL PF OR P IS A POSITIVE ENTIRE NUMBER, OF THE FIRST AND SECOND NARROW BAND FILTERS 2, 5, INSULATING THE MAIN RAIN OF RECEIVED SIGNAL R (T) AND SIGNAL TRANSPOSE D (T) RESPECTIVELY, MEANS 6 EVALUATION OF THE DPH PHASE DIFFERENCE WHICH EXISTS BETWEEN THE TWO FILTER SIGNALS AND WHICH IS A MEASUREMENT TO A COEFFICIENT G NEAR THE AMBIGUE DISTANCE. / P P APPLICATION TO RADARS WITH HIGH REPEAT FREQUENCY. / P
