The invention discloses a testing device and method for a ship radar system and belongs to the technical field of radar testing. The testing device comprises a to-be-tested radar transceiver, a displayer connected with the transceiver, and two corner reflectors having different sizes and mounted at the two different angles of the transceiver. The two corner reflectors are each provided with an AISantenna, and the two AIS antennas are connected with AIS equipment. An AIS antenna is mounted on the antenna position of the transceiver and connected with the other AIS equipment which is connectedwith the displayer, and the displayer is connected with an exterior power source. The distance between the corner reflectors and the radar antenna is large, the influence from weather factors such asrain, snow and the temperature is very small, the mounting position is conveniently selected, interference from other targets can be avoided, the positioning information of AIS is increased, it canbeensured that mis-judgment does not occur, the measuring accuracy and effect can be improved, and the testing input is greatly low.
Description
technical field [0001] The invention relates to a radar testing device and method, in particular to a testing device and method for a marine radar system, belonging to the technical field of radar testing. Background technique [0002] To test the performance of the marine radar system, under strict conditions, the overall system needs to be placed in a large microwave anechoic chamber, a receiver is installed to check the radar's transmission performance, and a microwave signal is sent through a signal source to check the radar's reception performance. [0003] The volume of the radar outdoor unit is relatively large, and the signal source and receiver used for testing need to maintain a minimum test distance from the radar. This requires a relatively large microwave anechoic chamber, with absorbing materials installed around it, and a very large investment in hardware and software. [0004] Generally, when testing, the user just places the system in an open place outdoors,...
