Detection Acceleration in Hough Parameter Space by K-Stage Detector

“…For determination of the non-radial trajectory, we replace the standard transform with polar Hough transform [5]. For detection acceleration we replace the fixed detection threshold in Hough parameter space with a sequential K-stage detector [6,7,8,9]. …”

“…This transform is very comfortable for use in radar detection and track determination, when the target changes its speed and flies at different azimuths. The principle possibility of minimizing the time of radar signal (target) detection by using sequential analysis in conditions of constant false alarm probability and detection probability, is discussed in [6,7]. The advantage of the sequential detector, if compared to the conventional detector, is in reducing of the radar energy at the radar target detection.…”

“…The advantage of the sequential detector, if compared to the conventional detector, is in reducing of the radar energy at the radar target detection. An important step in the development of an efficient approach for optimization and analysis of truncated sequential procedures is made by Sosulin in [6], within the study of K-stage procedures of statistical hypotheses test. Possible applications of such procedures, as well as optimization methods for various binary detection problems and multi-alternative detection problems are investigated in [6,8,9].…”

These papers illustrate the universality and efficiency of the developed approach to solutions of various truncated sequential detection problems and reveal the possibility to design K-stage signal detectors that significantly surpass in efficiency wide-spread detectors with fixed sample size.…”
