确实需要，参见 Resolution MSC. 193 (79), Performacne standard of Radar,
8 Interfacing
8.1 Input Data
. The radar system should be capable of receiving the required input information from:
a gyro-compass or transmitting heading device (THD);
a speed and distance measuring equipment (SDME);
an electronic position fixing system (EPFS);
an Automatic Identification System (AIS); or
other sensors or networks providing equivalent information acceptable to the Organization.
The radar should be interfaced to relevant sensors required by these performance standards in accordance with recognized international standards. see footnote
8.2 Input Data Integrity and Latency
8.2.1. The radar system should not use data indicated as invalid. If input data is known to be of poor quality this should be clearly indicated.
8.2.2. As far as is practical, the integrity of data should be checked, prior to its use, by comparison with other connected sensors or by testing to valid and plausible data limits.
8.2.3. The latency of processing input data should be minimized.
8.3 Output Data
8.3.1. Information provided by any radar output interface to other systems should be in accordance with international standards see footnote .
8.3.2. The radar system should provide an output of the display data for the voyage data recorder (VDR).
8.3.3. At least one normally closed contact (isolated) should be provided for indicating failure of the radar.
8.3.4. The radar should have a bi-directional interface to facilitate communication so that alarms from the radar can be transferred to external systems and so that audible alarms from the radar can be muted from external systems, the interface should comply with relevant international standards.
