Abstract:
A system for simulating a moving target for use with a Moving Target Indicator (MTI) radar, wherein said radar transmits a signal to said simulator which modulates a return signal 180.degree. out of phase with the radar-transmitted signal, said simulator comprising:an antenna for receiving energy from the radar;a directional coupler connected to said antenna;a detector connected to said directional coupler for detecting a signal from the energy received;a processor, wherein said processor further comprises cascading flip-flops, a first of said flip-flops being connected to said detector, and each of said flip-flops being connected to a selector having a selector output; anda phase-shifter connected to said selector output for phase-shifting a signal outputted therefrom, said phase shifter further comprising an output for providing a phase-shifted signal to said directional coupler and said antenna for transmission of the phase-shifted signal.
