Chi-Square起伏目標在秩二進積累檢測器中的檢測性能
DETECTION PERFORMANCE OF CHI-SQUARE FLUCTUATING TARGETS IN A RANK BINARY INTEGRATION DETECTOR
-
摘要: 正 近幾年來,非參量檢測逐漸被人們重視起來的主要原因是當輸入噪聲的分布相同和距離采樣各自獨立時,能保持虛警率恒定(CFAR)。秩二進積累(RQ)檢測器是在求秩后采用二進積累方法的一種非參量檢測器。這種檢測器實現(xiàn)較為簡單,檢測性能與秩和

Abstract: The formula of detection probability (Pd) of Chi-Square fluctuating targets in a rank binary integration detector is derived. The ealculation shows that asymptotic performance for the model targets is equal with asymptotic performance which is given in [1].Representative numberieal results are included to indicate Pd, which are computed by digital computer DJS-6. The optimal rank quantization is approximataly between 0.8(N + 1) and 0.9(N + 1) for N = 10, 16, 24; M = 16, 24; where N is the number of reference cells, M is the number of radar's pulse repetition rate. -
