Abstract
A variable radar altimeter test system for providing a test of the altime portion of a flying object guidance system which simulates actual flight conditions includes an antenna connection to receive a signal from the flying object being tested, a synthesizer for generating a signal programmed to simulate data characteristic of a radar return signal, pulse modulation of the programmed signal to create a third signal which is returned to the flying object under test to stimulate the altimeter portion of its guidance system.
Claims2
An apparatus for testing the altimeter portion of the guidance system of a flying object during a simulated flight including,
- means for detecting the envelope of a signal received from the flying object under test,
- means including a programmable synthesizer for creating programmable signal,
- means for pulse modulating the programmable signal with the envelope of the signal from the flying object to create a third signal,
- and means for transmitting the third signal to the flying object to stimulate the altimeter portion of the flying object guidance system.
