ABSTRACT:
A pulse-generation means produces RF pulses that are injected into the ra receiver. A range control means and an attenuation control means selectively vary the range and the signal strength of the RF pulses in either a manual or an automatic sequence. A display and evaluation means determines the signal strength at which a radar tracking lock is established and compares that signal strength with a standard to provide an indication of receiver operability.
