Electronic target radar simulator

A method of electronically simulating an actual missile-radar target encounter for testing said missile-radar comprising the steps of:

• collecting data pertaining to target signature at a reduced relative encounter velocity between a modified missile radar and an actual target;
• recording data pertaining to independent amplitude and phase signals of said target signature from outputs of said modified missile radar and simultaneously recording data pertaining to target distance;
• loading data comprising amplitude and phase measurements pertaining to said target signature into Programmable Read Only Memories in an RF Loop which is part of a simulator;
• coupling said modified missile radar to the simulator by means of an anechoic chamber or space hood;
• calibrating the RF Loop of the simulator by means of amplitude and phase adjustments so that the outputs of said modified missile radar replicate the outputs of said modified missile radar during data collection at a reduced relative encounter velocity;
• scaling the output of said modified missile radar coupled to said simulator to actual encounter velocity;
• coupling a missile radar to be tested to the simulator in the same manner as the modified missile radar;
• initiating a test sequence wherein the loaded Programmable Read Only Memories modulate the received radar signal in the RF Loop of the simulator,and wherein a clock counter is started;
• providing a video output from the missile radar being tested to indicate when the missile radar threshold is exceeded, and
• correlating the number of clock pulses counted by said initiated counter with target distance to determine missile lethality.
