Abstract
Tong detection algorithm is a common used signal detection algorithm. But the overall conclusions about statistical performance and parameter setting of Tong detection algorithm are absent. Aiming at these problems, statistical and recursive analysis methods were used to carry on theoretical analysis about mean value and variance of dwell times in signal search unit in detail, the corresponding expressions were given, a maximum dwell times constraint method was offered according to the 3Sigma principle. The relationships between detection probability, average dwell times of noise search unit and signal search unit, initial value and maximum value of algorithm counter, pre-detection signal to noise ratio were analyzed. Analysis results indicate that the parameters of Tong detection algorithm should be set according to signal strength and search modes, and the influence of parameter setting on detection probability and average dwell times of noise search unit or signal search unit should be balanced.
