Abstract :
This letter presents an extension of the Multifamily Likelihood Ratio Test (MFLRT) so it can be applied for detection of a deterministic signal of unknown waveform using measurements from multiple sensors. The extended MFLRT is applied for precipitation detection from noisy measurements of the received signal level (RSL), taken from commercial microwave links (ML). The extended MFLRT shows improved detection performance compared with the existing standard Generalized Likelihood Ratio Test (GLRT), while offering also the ability to estimate the signal waveform.
