Detection Platforms

Platforms for detecting, identifying and/or designating objects. Platforms according to one embodiment of the invention include an extendable mast connected to a skid via a linkage that allows pivoting of the mast with respect to the skid, and preferably does not permit rotation of the mast; at least two actuators connected to the mast; at least one inclination sensor; at least one detection sensor connected to the mast for detecting presence of an object; and circuitry that receives information from the inclination sensors and plumbs the mast. Coupling and actuator mechanisms are disclosed for connecting the mast to the skid in a manner that allows the mast to be stable for accurate use of the sensors, yet easily and quickly deployable for such use, whether the platform is deployed from the bed of a truck or when the skid is on the ground and the mast is fully extended.
