Radar Pulse Measuring

The system determines distance by measuring the time increment between transmitted and received pulses of a pulse radar system,

Crystal oscillator 2 is the master timing control. One of its outputs serves as the PRF timing source 4. Oscillator 2 also feeds directly into gated coarse counter 6 and into gated constant current generator 8 Gate 10 is turned on by PRF 4 and turned off by the pulse received from radar receiver 12, Generator 8 alternately applies and withdraws a constant current to and from a store circuit 14, The latter is essentially a capacitor, Sampler 16 reads the value of the charge on store 14 at the time of the received pulse, This charge value is then converted in encoder 18 to a binary number which is added to the number from coarse counter 6. The binary number at output of adder 20 represents distance.
