The effect of noise on pulsed rate-tracking sytems with correlation discriminators

A theoretical study shows that the main cause of the disruption of tracking in a pulsed rate-tracking system with a correlation discriminator in the presence of noise is a decrease in the slope of the discriminator curve, and not an increase in error fluctuations. This is why this type of tracking system under the effect of noise loses its ability to track a target in dynamic conditions, when the target moves with an acceleration, producing a change in the Doppler frequency of the reflected signal.
