Title:
DIGITAL FULL-BROADBAND DIRECT-FORWARD-TYPE SEARCH AND RESCUE RADAR TRANSPONDER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/240957
Kind Code:
A1
Abstract:
Provided in the present invention is a digital full-broadband direct-forward-type search and rescue radar transponder (SART) system. A brand-new SART system architecture and a new code recognition solution corresponding to the SART system architecture are provided. In the present invention, a direct-forward-type system architecture is used in the system, and digital broadband DRFM real-time forward technology and a discontinuity code response architecture are combined in the architecture. Transceiving antennas are independent of each other and work simultaneously, and all radar interrogation signals in a working frequency band are directly and indiscriminately coded and forwarded, such that complete waveform information is reserved and response information is coded. The system in the present invention may be equivalent to an object having a special object characteristic, such that an echo signal having a fixed code modulation characteristic is generated after a radar signal in a working frequency band is transmitted to the object.
