20110227778 | Hand-Held See-Through-The-Wall Imaging And Unexploded Ordnance (UXO) Detection System - The housing of a portable radar unit includes features for providing positioning of auxiliary handles between a first position and a second position, in which: the first position places the auxiliary handles in a position to act as handgrips in conjunction with integral handles and the second position places the auxiliary handles at an angle to the integral handles, so that the radar unit can be held with one hand and supported by a forearm of the same hand. Rotation of each auxiliary handle about a pivot moves the auxiliary handle between the first position and the second position; and a friction mechanism resists the rotation so that the auxiliary handle tends to stay in position until purposefully moved. The housing also includes internal space for housing a radar antenna, a reflector, and a mechanism for adjusting distance between the reflector and the antenna for tuning performance of the antenna. The housing provides external access without intrusion into the housing for operating the adjusting mechanism. | 09-22-2011 |
