Abstract: A programmable radar target simulator provides microwave signals for testing a missile that is otherwise controlled by such signals when it is deployed. The simulator has the capability for initiating suitable microwave signals at the proper power levels in the fully automatic, semi-automatic, or fully manual modes. A control section and an IF section accept digital commands from an external computer or manual control from switches and thumbwheels on the front panel of the simulator to provide for the automatic and manual control signals respectively. A frequency synthesizer section provides three frequency modulated IF signals and one amplitude modulated coding signal which respectively are fed to the IF section and to the control section. Doppler frequency shifts are extracted and representative signals are provided in both AC and DC forms to a microwave section.

Abstract: A phase noise analyzer uses a microwave section to produce a standard reference voltage which is filtered by a sequenced pair of frequency agile filters. The filter output is fed to an indicator which is calibrated to the desired units.
