Abstract
A test system simulates a moving target for a radar system under test. The test system includes a Doppler simulation circuit, coupled to an input, to apply a frequency shift to RF pulses received on an RF signal generated by the radar system to simulate speed. A signal delay sub-system produces a delay in the RF pulses to simulate distance. A pulse detection circuit is to detect time of receipt of the RF pulses, including a first time of receipt of a falling edge of a first RF pulse. An I/O controller updates a value of the frequency shift for the Doppler simulation circuit and of the delay for the signal delay sub-system during a time period between the first RF pulse and one of a second RF pulse or a second time at which the second RF pulse should have been received in case of a missing pulse.
