Which type of radar most frequently triggers the racon signal from a sea buoy?

The type of radar that most frequently triggers the racon signal from a sea buoy is the 3 cm radar. Racon systems, which are radar beacons used for navigation, are typically designed to respond optimally to specific radar wavelengths. The 3 cm radar, which operates in the Ku-band, aligns well with the design of many marine radars that are commonly used for navigation and can provide effective range and resolution.

The nature of the 3 cm radar allows for reliable identification and response from the racon beacons, which send a coded signal back to the radar, facilitating the identification of buoys and enhancing navigational safety. While the 10 cm radar operates effectively and can also be used with racons, it is generally not the most commonly associated type that triggers these signals as frequently as the 3 cm radar does.

In summary, the 3 cm radar is particularly suited for triggering racon signals due to its operational characteristics in the maritime environment, which are compatible with the functionality of the racons installed on sea buoys.
