Abstract:

This report is concerned with an experimental evaluation of the probability of interception of a pulsed radar signal by periodically tuned intercept receivers. The problem has been attacked by simulating the radar transmitter and intercept receiver characteristics with electronic equipments providing pulse trains representing 1 the time interval during which the radar transmission is directed toward the receiver, and 2 the time interval during which an intercept receiver employing a directional receiving antenna is responsive to the incoming radar transmission. An interception of a radar transmission by the receiver is indicated by a finite time coincidence of these pulse trains. By a method of counting the pulses actually appearing in the simulated receiver circuits, the effectiveness of the operation is measured by determining both the time distribution and percentage of radar pulses intercepted.
