Abstract
A one-piece traffic radar unit has a housing containing both the transceiver and signal processing circuitry and the directional antenna of the radar system. A bracket plate extends from the top portion of the housing and overlies the dashboard of the patrol vehicle to mount the unit therein with the housing depending from the bracket plate in front of the dashboard, thereby leaving the driver's view through the windshield unobstructed. The antenna is of the conical horn type and is vertically disposed to beam the transmitted signal up through the housing to a rotary reflector mounted on the top of the housing. The reflector is rotatable about a vertical axis and permits the operator to aim the beam in any horizontal direction through the windshield or a window of the vehicle. A special safety mount for the reflector provides for 360.degree. rotation and also permits the reflector to break away from the housing on impact. The housing is specially shaped in that the front panel thereof, containing the controls and readout, is positioned obliquely with respect to the fore-and-aft axis of the vehicle to face the panel generally toward the driver and provide a convenient reading angle.
