Abstract: A system and method emulate an echo signal from an emulated target in response to a radar signal from a radar DUT. The system includes an antenna configured to receive the radar signal, and to direct a reflected portion of the radar signal away from an incident direction of the radar signal at a predetermined deflection angle to prevent the radar DUT from receiving the reflected portion; and a transceiver configured to provide an RF signal having an RF frequency shifted from a frequency of the radar signal in an amount indicating a distance to the emulated target, and to transmit the RF signal to the radar DUT as an emulated echo signal. An antenna pattern includes a peak beam angled away from a normal incidence of the antenna at a beam squint angle that compensates for the predetermined deflection angle to direct the peak beam toward the radar DUT.

Abstract: A miniature radar target simulator (MRTS) and a system comprising a plurality of MRTS's are described. The MRTS and system are useful for emulating echo signals for a radar DUT with reduced interference. Illustrative radar test systems desirably generate the intended (emulated) radar targets and reduce unwanted (“ghost”) signals, which can result in “ghost targets,” and errant/ambient electromagnetic radiation that reduces the performance and reliability of known re-illuminators and systems including same.
