WebThe analysis shows how the idea of threshold detection arises. The strategy for determining threshold levels and predicting detection and false alarm performance is demonstrated, … WebAs in the case of nonfluctuating targets, you have approximation equations to help determine the required SNR without having to plot all the curves. The equation used for fluctuating targets is Shnidman's equation. For the scenario used to plot the ROC curves, the SNR requirements can be derived using the shnidman function. sprintax help

WebBiography. David A. Shnidman (S'65—M'66—L'02) was born in Boston, MA. He received his B.S. and M.S. degrees in electrical engineering from the Massachusetts Institute of Technology (M.I.T.), Cambridge, MA in 1959 and Ph.D. degree in applied mathematics from Harvard University, Cambridge, MA, in 1965. He is currently working as a consultant. WebThe results of these papers are updated by redoing the relevant equations with more appropriate clutter density functions, that are normalized with respect to the receiver noise, as is done with the target models.
