GLR test for minimum detectable velocity indication in OFDM radar
Minimum detectable velocity (MDV) of the target is always regarded as an important parameter in radar system that depends on an acceptable signal-to-interference ratio (SIR) loss. In this paper, we point out an asymptotically equivalent relationship between the generalized likelihood ratio (GLR) and the SIR for orthogonal frequency division multiplexing (OFDM) radar system. This relationship can simplify the post-signal processing procedure of moving target illumination, which makes the MDV could be obtained in parallel when detecting the target without separately calculating the SIR.
