Multiple-stage detection systems which allow stage -to -stage changes in 

 the radar characteristics and in the statistical decision process are described, and 

 the literature on such systems is briefly reviewed. A binomial two-stage detection 

 system with coarse-fine resolution is then outlined and the optimization of some of 

 its design parameters considered, with appropriate curves given. Some special 

 cases of these binomial two-stage detectors are investigated in detail; for these, 

 detection probabilities and optimum design parameters are plotted as functions of 

 other design parameters and of the signal strength, and comparisons made with a 

 conventional detection method.
