Abstract: A motion compensation unit and method for use in a radar system. The motion compensation unit comprises a match filter module for producing filtered range-pulse-sensor data; a motion information module for providing motion information related to motion of the radar system; a motion compensation beamformer module connected to the match filter module and the motion information module for utilizing the motion information to provide motion-compensated range-pulse-azimuth data; and, a Doppler processing module connected to the motion compensation beamformer module to provide motion-compensated range-Doppler-azimuth data.

Abstract: A quick release latched security window guard having a framework attached to a building exterior overlying a window is held with a cam latch system including a cam rod extending through the building wall, with an end protruding into a hollow member forming a part of the framework. A sliding latching sleeve is spring urged into a slot in the cam rod end to lock the framework in place. Rotation of a handle on the rod end within the building forces the sleeve back to be cammed out of the slot to release the framework. One or more fixed slotted latching posts may also be mounted to protrude into the hollow member and to be engaged by portions of the sleeve to form additional latching points, all of which are released by the rotation of a single cam rod. The framework may take the form of one or more ladder sections deployed to hang down from the window when the framework is pushed out after being released by the operation of the cam rod.
