Abstract
A system and method are provided for emulating an echo signal reflected from a diffuse target, having an indeterminate shape and range in a radar environment, in response to a frequency-modulated continuous-wave (FMCW) radar signal transmitted by a radar under test. The method includes receiving the FMCW radar signal from the radar under test, the FMCW radar signal having radar signal frequencies linearly modulated between a first frequency and a second frequency; generating a bandlimited noise-like signal having frequencies within predetermined frequency limits, and a spectral shape such that amplitudes of the noise-like signal vary in a predetermined manner with respect to the frequencies; mixing the noise-like signal with the received FMCW radar signal to provide an emulated echo signal reflected from the diffuse target; and transmitting the emulated echo signal of the diffuse target to the radar under test.
