CHAPTER 12
GLRT Detection Schemes
In many radar systems, target detection is carried out by the sequential application of adaptive filtering to the input data, followed by constant false-alarm rate (CFAR) processing on the amplitude of the filter output, as two separate steps prior to sample thresholding. The former attempts to maximize the signal-to-disturbance ratio (SDR) of the scalar samples at the filter output, while the latter aims to normalize the envelope of the output sequence based on estimates of the mean disturbance level, such that a fixed threshold setting may be used to maintain a constant and predictable false-alarm rate.
