Analytic Performance Evaluation Design of the MFACP CW Normalizer
Abstract
An analytic performance evaluation methodology of the Mid-Frequency Active Classification Processor Continuous Wave (MFACP CW) phase 1 normalizer algorithm is presented. This normalizer uses a recursive structure with an exponential filter for estimation of the mean background level of the cell under investigation. The methodology allows the determination of the expected value and variance of the normalizer mean estimate which are the essential parameters of the probability of false alarm P(F) and detection P(D) expressions from which Receiver Operating Characteristic (ROC) curves can be computed. The signal processing prior to the normalizer consists of a Fast Fourier Transform (FFT) with 75% overlap windowed data (Rectangular or Hanning) and and envelope detector. The analytic expressions derived are done specifically for 75% overlap but are general enough so that different overlapping or windowing are applicable with minor modifications.
