The cumulative detection probability for a search radar is a function of target approach angle as well as other radar and target parameters. Earlier studies have dealt with radially approaching targets; this one deals with nonradial target approach angles. From the curves in this Memorandum, optimum scan rates and the relationship between cumulative detection probability and normalized range can be determined. Both nonfluctuating and fluctuating target cases (Swerling Cases I and III) are considered. The FORTRAN program for these calculations is included and can be used to compute cumulative detection probabilities for other target approach angles and scan rates.
