ABSTRACT:
In the error sensor system for range tracking, incoming radio frequency pes are coupled into two gates, an RF gate and an early-late gate. The signals are then processed and summed in quadrature to provide measurement of time alignment error between the RF pulses and a time reference for range tracking. Quadrature summing of the signals allows the time alignment error to be encoded as a phase angle which allows error decoding between the incoming radar frequency and the range tracker gating period, the alignment error being resolved by phase detecting the amplitude limited signal output.
