Forward deployed sensor system

A method of operating a submersible system comprising:

• providing:
• a system body having an adjustable buoyancy system enabling the system body to float at or beneath a water surface;
• a sensor array including a radar sensor;
• and
• a sensor array raising system coupled to at least a top surface of the system body and the sensor array, wherein the sensor array raising system is configured to selectively raise and lower the sensor array with respect to the system body and the water surface in order to selectively enable operation of the sensor array above the water surface,
• wherein the sensor array raising system comprises:
• at least a first arm and a second arm, the first arm having a first end rotationally coupled to a top surface of the system body with a first pivot joint and a second end opposite the first end of the first arm that is rotationally coupled to a first end of the second arm with a second pivot joint, and the second arm having a second end opposite the first end of the second arm that is rotationally coupled to the sensor array with a third pivot joint;
• raising the sensor array with the sensor array raising system;
• and
• initiating detection for at least one object using the sensor array.
