FIELD: radar systems. SUBSTANCE: the tracking radar range finder has a three-channel time discriminator consisting of the main and two watch channels connected to the target signal and range pull-off detectors, relative target range drivers and the main channel filter, target pull-off compensators forming the target range estimates observed in the watch channels; analyzers of the estimates of target range and its derivatives in which the presence of the true target is decided; a logic unit that produces the target range estimate to the gating circuit and the main channel filter, commutator providing for transmission of target range estimates and its derivatives to the user. EFFECT: enhanced noise immunity of tracking range finder in a complicated noise-target situation. 3 dwg
