Claim:
1. An apparatus for creating microwave radiation patterns for an object detection system, comprising: a waveguide conduit having a plurality of first slots at one side of the waveguide conduit and a plurality of corresponding second slots at an opposite side of the waveguide conduit, said waveguide conduit being coupled to a microwave source for transmitting microwaves from the microwave source through the plurality of first slots; a plunger moveably positioned in the waveguide conduit from one end thereof, said plunger allowing the waveguide conduit to be tuned to generally optimize the power of the microwaves exiting the plurality of first slots; and a plurality of secondary plungers, each fitted in one of said plurality of second slots to independently tune or detune microwave emittance through a corresponding first slot.
