Abstract

We detail a delta-sigma based system built to produce high-resolution analog waveforms at UHF. With bandwidths as large as 80 MHz and noise floors as low as -140 dBc/Hz, the generated waveforms show potential for use as LO and RF transmission waveforms in a UHF radar system. Finally, the waveform generator system is described as an ideal technology for use in a digital phased array radar.

Mr. Richard M. White - Naval Research Laboratory

Richard White received his BSEE degree from the University of Maryland in 2001. He has since worked in the Radar Division of the Naval Research Laboratory in Washington, DC. His main area of focus is in analog and digital design.

Dr. Ben H. Cantrell - Naval Research Laboratory

Dr. Ben H. Cantrell received the degrees of BSEE and MSEE, 1964 and 1967 at Wichita State University and Ph.D., 1970 at the University of Pittsburgh. Dr. Cantrell has been at the Naval Research Laboratory since 1971 and was a Branch Head in the Radar Division from 1987 until 2001 when he assumed his current position as Radar Chief Scientist. Dr. Cantrell has worked in the areas of detection, estimation, signal processing, radar design, radar analysis, simulation, etc. A few past contributions are providing automatic detection and tracking to the fleet in the 1970?s, Radar Detection of Low Observable Targets in the presence of severe clutter to the fleet in the 1980?s, and timely detection of high-speed sea skimmer threats in the 1990?s. This work has all been transitioned to the AN/SPS-49A and the SPQ-9B radars respectively. Dr. Cantrell has also taught at Wichita State University, the University of Pittsburgh and worked for Boeing.

Mr. James J. Alter - Naval Research Laboratory

James J. Alter received the B.S.E.E. and M.S.E.E. degrees from the University of Maryland in 1973 and 1981, respectively. He has worked in the Radar Division of the Naval Research Laboratory since 1973, where he is currently Head of the Advanced Radar Systems Branch. His main area of interest is in the development of real-time radar signal processors.
