Abstract

A remotely controllable, tiltable platform supports a radar transmitter/receiver for rotational movement of the radar relative to a mounting on a vessel, such as a mast of a sailboat or the superstructure of a power boat. A cowling extends upward from the foundation plate and a stationary hinge plate, parallel to the foundation plate, is secured to the top of the cowling. A top antenna mounting plate is hingedly secured to the stationary hinge plate. An actuator is positioned within the cowling to controlled movement of the top antenna mounting plate to maintain the radar level with the horizon. Alternatively, an A-frame structure mounts the leveling system to a mast of a sailboat.

Claims

1. A radar antenna leveling system for a vessel comprising:

a tiltable platform system comprising;

a foundation plate secured to the vessel, the foundation plate having an upper surface;

a lower actuator mounting plate secured to the upper surface of the foundation plate;

a stationary hinge plate parallel to the foundation plate, the stationary hinge plate having an under surface;

a top antenna mounting plate secured hingedly mounted to the stationary hinge plate for rotational movement therewith, the top antenna mounting plate having an under surface;

an upper actuator mounting plate secured to the under surface of the top antenna mounting plate; and

a cowling secured to the upper surface of the foundation plate and to the under surface of the stationary hinge plate, the cowling having a hollow interior;

an actuator secured to the lower actuator mounting plate and to the upper actuator mounting plate for rotational movement of the top antenna mounting plate relative to the vessel, wherein the actuator extends through the hollow interior of the cowling; and

control remote from the actuator for operation of the actuator.

2. The system of claim 1, further comprising a flexible joint securing the actuator to the lower actuator mounting plate.

3. The system of claim 1, wherein the control includes operator selectable controls to move the top antenna mounting plate up, down, and automatically control the leveling of the system.

4. The system of claim 1, further comprising an inclinometer secured for movement with the top antenna mounting plate.
