Abstract
A digital full-bandwidth direct-forwarding racon system and a working method adopt a direct forwarding architecture, which combines a digital broadband DRFM real-time forwarding technology and an encoding response architecture with dots replacing a line. A transmitting antenna and a receiving antenna operate independently and simultaneously, and directly and indiscriminately encode and forward all of the radar query signals in an operating frequency band, thus preserving complete waveform information while realizing a Morse encoding of the response information. The digital full bandwidth direct forwarding racon system is equivalent to a target with a special target characteristic, where when a radar signal within the operating frequency band irradiates the target, an echo signal with a specified Morse encoding modulation characteristic would be generated.
