ABSTRACT:
Improved acquisition of signals in a Gaussian noise environment is achieved by applying the output of a correlator (14) to a threshold detector (12). A correlation pulse output from the threshold detector (12) and the output of the correlator (14) are input to a false alarm processor (10) that includes multiple correlation checking channels (22). Each correlation checking channel (22) is assigned to sample an input at various points over a selected interval by an enable pulse generated at the output of select logic (30). Each correlation checking channel (22) includes correlation check enable logic (34), a blanking generator (36), and a confirmation logic (42). In the confirmation logic (42) samples of the analog input are taken at discrete times and integrated over a preselected number of intervals. If this integrated value exceeds a threshold level during the integration interval, the analog input signal is considered valid and a "signal confirmed" pulse is generated and gated through a gate NAND (44) onto a signal confirm line 28.
