Latest Patents
Garrard holds a patent for a Millimeter Wave Length Guidance System. This high-frequency target-seeking device utilizes a stabilized reflector antenna to perform range search and tracking functions, as well as target angle search and tracking functions. The system incorporates a technique for target range discrimination using several narrow band intermediate frequency filters, which improves the signal-to-clutter ratio and the signal-to-receiver noise ratio. The device accomplishes target search through simultaneous range and antenna azimuth scanning, sweeping the range bins and antenna beam across the target. A multiplexer selects the range bin that indicates the target, while target range tracking is achieved by the multiplexer automatically selecting adjacent range bins and comparing their output signals. Antenna stabilization is facilitated by signals from vehicle pitch, roll, and yaw rate sensors, along with antenna elevation and azimuth rate and angle sensors. These signals are processed in the antenna control circuit to provide the desired stabilization.
