Latest Patents

Among his latest patents is a groundbreaking ground-based pulse radar system and method that provides high clutter rejection. This MTI radar system transmits pulses with variable interpulse time periods and utilizes a lattice filter to process return signals. It effectively identifies targets while substantially rejecting both static and moving clutter. Additionally, the system is designed to mitigate the adverse effects of transmitter instability during the processing of return signals. This innovative radar system is particularly applied in airport traffic control, where it detects aircraft as targets.

Another significant patent is the steerable disk antenna, which is adapted for use on aircraft for surveillance purposes. This radar antenna system features a nonconducting disk radome structured with aerodynamic fairing to minimize aerodynamic drag. It employs a series of struts to secure the disk radome to the aircraft, maintaining a solid horizontal reference plane. The design includes elongated, low-gain radiating elements distributed across the disk radome, which radiate generally in the vertical direction. An electronic system within the ground-plane box supports transmit/receive circuits that facilitate communication with the radiating elements.
