This paper presents results of a study to assess the impact that sequential detection has on the performance of the twolevel frequency hopping coarse acquisition detector. The performance of the two-level detector is computed for the case where the active correlators use sequential detection and compared to the conventional case where fixed correlation times are used. The results show that sequential detection can significantly reduce the amount of hardware required to achieve a specified probability of detection in the presence of AWGN and partial band noise jamming under normal operating conditions; however, when the signal-to-interference level is low andlor the required detection probability is high, sequential detection requires more hardware than ked detection.
