FIELD: radar systems; search of signals of radar systems, type LORAN-C. SUBSTANCE: in detecting the signal by main algorithm, search interval position is introduced in third memory unit; introduced in memory unit is interval during which event took place for the first time, i.e. on front of the envelope of strong signal. In course of realization of auxiliary algorithm, switching unit together with control unit excludes any change in content of third memory unit due to which in taking the decision on detection of signal of master station, magnitude of position number will be furnished to consumer from third memory unit, not from second memory unit; this magnitude corresponds to maximum magnitude of accumulated decoded access, i.e. to maximum of the envelope of signal. Signal detector is additionally provided with switching unit and third memory unit connected in series. Signal input of memory unit is connected with output of second memory unit and output is connected to signal input of unit and input of switching unit is connected with additional output of control unit. EFFECT: high reliability of detection at reduction of time of search of specific point of the envelope at stage of resolving ambiguity in case of strong signal. |
