Improved Radar Range-Gated MTI Processor.
Charles James Boyle · Calhoun: The Naval Postgraduate School Institutional Archive (Naval Postgraduate School) · 1975
A redesigned timing circuit and improved handpass filters were constructed and integrated with the MTI range-gate-and-filter modification kit for the Naval Postgraduate School AN/UPS-1D radar. Principle improvements allow operation is a jittered PRF mode and increased effectiveness of channel filters through the use of active fifth-order Butterworth analog filters. The design objectives were to achieve the elimination of blind speeds, improved frequency response of the channel filters and the reduction of the MTI minimum discernible signal.
