Abstract
Abstract IN A RADAR RECEIVER A REFERENCE VOLTAGE IS GENERATED TO PROVIDE A CLIP LEVEL FOR RECEIVED SIGNALS. THE SIGNALS WHICH EXCEED THE CLIP LEVEL ARE USED TO GENERATE A PULSE COUNT WHOSE VALUE IS A FUNCTION OF THE TIME DURATION OF PASSED SIGNALS DURING A PORTION OF THE PERIOD BETWEEN TWO RANGE PULSES TRANSMITTED BY THE RADAR TRANSMITTER. A POSITIVE OR NEGATIVE SIGNAL IS GENERATED IN ACCORDANCE WITH WHETHER OR NOT THE ACTUAL COUNT VALUE EXCEEDS A GIVEN COUNT VALUE DURING THE PERIOD. THE SIGNAL SO GENERATED IS INTEGRATED TO PROVIDE THE REFERENCE VOLTAGE FOR THE NEXT PERIOD.
