The invention discloses a radar responder with a high transmission power. The radar responder includes a frescan which is connected with a transmitter, a loop detector and an antenna sequentially. A receiver is also arranged between the frescan and the loop detector. The transmitter includes a VCO processing circuit, a power amplifying and matching circuit and a power-supply management unit. The VCO processing unit is connected with the power amplifying and matching circuit. The power-supply management unit includes an energy-saving controller and a power-supply converter, which are connected mutually. The VCO processing circuit includes an oscillation circuit comprised of a VCO (voltage controlled oscillator) device. The radar responder with the high transmission power realizes increase of the transmission power of RF signals of the radar responder and ensures meeting of requirements of enlargement of the coverage range of the RF signals so that rescue speed is faster and at the same time, rescue boats can locate the distress location of a boat more rapidly and accurately so that rescue efficiency is improved significantly and the device is sensitive in response and simple to maintain and thus rapidness and accuracy in a boat rescuing process are ensured.
Description
technical field [0001] The invention relates to a radar transponder, in particular to a radar transponder with relatively high RF signal transmission power. Background technique [0002] The radar transponder is the main equipment used in the GMDSS system to determine the position of ships in distress, lifeboats and survivors. Radar transponder is a device used at the scene of a distress, which enables search and rescue aircraft or ships to search for victims as soon as possible, and allows survivors with radar transponders to know whether there is a rescue aircraft or rescue ship approaching them. With the rapid development of ship communication and navigation, the functional complexity of communication and navigation equipment is increasing, and the regulations on safety, stability and energy saving are becoming increasingly stringent. However, the existing radar transponder RF signal coverage is limited, that is, the distress signal sent by the distressed ship is limited...
