An evaluation of the performance of several sequential detectors for the case of incoherent detection; that is, when the pulse-to-pulse radar returns are independent observations on the envelope of a sine wave in narrow-band Gaussian noise. Two sequential probability ratio tests (SPRTs) and the biased square law sequential detector (BSLSD) were compared for blip/scan ratio and average test time for static and fluctuating targets at known range. The SPRT for Swerling's Model II fluctuating target is the preferred sequential test; it gives a 4 to 7 db improvement over the optimum fixed-duration tests. Wald's approximations for SPRT evaluation were compared with the exact results and found to be inadequate for large signal/noise ratios. The APRST and MPRST (averaged and maximum probability ratio sequential tests) were evaluated and compared with optimum fixed-duration tests for unknown range conditions (multiple range resolution cells).
