본발명은레이더신호처리기술에관한것으로서, 더상세하게는바이스태틱레이더환경에서재머로인한 DOA(direction of arrival)를구별하고표적 DOA와 DOD(direction of departure)를추정하는방법및 장치에대한것이다. 본발명에따르면, 재머가존재하고임의의 2차원또는 1차원안테나배열을갖는바이스태틱레이더환경에서수신신호로부터표적에의한 DOA(Direction Of Arrival)와재머로인한 DOA를구별할수 있다.
Abstract:
An apparatus for modulating pulse using a light wave delaying device is provided to form shuttle light transmission paths using passive optical elements(optical simulator and optical mirror), thereby reducing the size of the apparatus and reducing manufacturing cost. An apparatus for modulating pulse using a device for delaying light wave comprises the followings: an optical simulator(10) having an input port for inputting an optical signal, a delay port for delaying the optical signal, and an output port for outputting the optical signal; an optical delay unit(20) having an optical delay unit to be connected to the delay port; a first switch for switching signal input; an optical converter for converting a signal passed through the first switch into an optical signal; a photoelectric converter for recovering an optical signal delayed in the optical delay unit; and a second switch.
