Description
The {blockLibraryPP_blocksPP_FF_PhasedSS_ArraySS_SystemSS_ToolboxFF_DetectionFF_GLRTSS_DetectorPP_label} detects signals with unknown parameters in the presence of noise. Unknown parameters include amplitude, phase, frequency and time of arrival. The detector replaces the unknown parameters with their maximum likelihood estimates under the hypothesis of no signal and the alternative hypothesis of signal presence . The binary detector then chooses between the null hypothesis and the alternative hypothesis based on the measurements. If hypothesis best accounts for the data, the detector determines that the target is absent. If the hypothesis best fits the data, the detector determines that the target is present.
