Spin Frequency Detection in the Spectral Domain.

Abstract

This research involves the development, implementation and optimization of algorithms for tracking the spectral spin frequency representations of a revolving cylindrical target having four protruding scatterers. The investigation is limited to coherent phase and amplitude data that are constant to within a few millimeters per second with respect to the base of the cylinder, spin frequencies between five and fifteen Hz, and an absolute spin frequency rate of change less than 1.25 Hz per second. The research was conducted such that the algorithms and procedures that were developed could be performed by analysts who are relatively unskilled in this analysis. The heuristic methodology utilized in this effort is one wherein a working model of the expert analyst's problem-solving approach is obtained by observing him perform the manual procedure, generating the associated protocols, and then programming this intelligence into the machine. The manual procedure was easy to understand and to implement in the machine.
