This correspondence deals with the effect of multiple signals on the control voltage of the delay-lock discriminator (tracker). Given n returned signals with known delay and power, a formula for the tracker estimate is derived. The analysis has specific application to low-altitude altimeters where the leak signal from the transmitter to the receiver may have delay comparable to the delay of the true signal.
