Detection and Tracking
John C. Toomay, Paul J. Hannen · Institution of Engineering and Technology eBooks · 2013
Assume that radars having some of the parameters described in the preceding chapters can be built and operated. A vitally important question is how the operator decides when he sees a target. He has found out quickly from experience that he can turn up the gain on his radar display and completely fill his field of view with false targets (noise), or he can turn down the gain and eliminate all targets. How does he decide where to set the threshold to optimize his ability to detect? Likewise, how do we set the threshold for the automatic detection systems used by the majority of modern radar systems?
