Abstract : A method was devised for calculating the detection probabilities for a scanning radar employing feedback integration. The optimal value of K, the feedback value, is determined by equating 1/(1-K), the equivalent number of pulses integrated, to 63% of the number of pulses between the 3-dB points of the scanning antenna. This expression holds for small- and large-sample sizes and for fluctuating and nonfluctuating targets. Then, by subtracting an antenna beam-shape factor of 0.3 dB from the midbeam signal-to-noise ratio, one can use the standard detection curves to find the probability of detecting a target as it passes through the beam. The beam-shape factor differs from 0.3 dB by less than 0.2 dB for small-sample sizes. (Author)
