The patent describes a circuit to provide an automatic range tracking function in very high resolution short pulse radar or missile seeker. A tracking gate is generated by feeding the output of the oscillator for the transmitter trigger generator through a continuous phase shifter and binary counter to generate a gating pulse. An early-late tracking discriminator updates a velocity memory circuit that feeds a variable speed drive motor to drive the continuous phase shifter which completes a closed tracking loop. The tracking discriminator can be of an adaptive type that tracks a particular desired point on a compound target.
