Phased array antennas are in widespread use for radar systems and other applications. This presentation
will briefly review the fundamentals of radar operation and present some example radar systems. The
presentation will then highlight some of the fundamental design trades involved in applying phased arrays
to radar systems. Topics will include element and array design, architecture trades, beamformer options,
active element impedance, excitation error budgets and their effect on array pattern performance, power
handling and power distribution.

Donald McPherson

Biography:

Donald McPherson has more than 30 years of experience in RF, microwave and antenna engineering from 400 MHz to 94 GHz. He joined SRC, Inc. in 1995 as a Sr. Research Engineer. He served as manager of RF Design from 2002 to 2012 and since 2013 has been a Sr. Principle Research Engineer, retiring in 2020. He has contributed to numerous phased array radars including an S-Band multi mission radar, an L-Band counter mortar radar and a UHF foliage penetration radar. He has further led the design of an X-Band multi-beam phased array, implemented calibration of a 94 GHz active phased array and led the investigation of wideband phased array concepts.
Prior to joining SRC, Mr. McPherson was a Sr. Microwave Engineer at the Lockheed Martin (General Electric) Electronics Laboratory. He was engaged in phased array antennas at 20, 44, 60 and 94 GHz. He contributed to T/R module developments at C-Band and L-band for ground and space applications. In addition, he designed MMIC amplifiers at X and Ku-band. He was previously employed at Anaren Microwave as a Co-op Engineer. Mr. McPherson received an AAS from SUNY Alfred in 1980, a BSEE from Rochester Institute of Technology in 1984 and an MSEE from Syracuse University in1989. He is a senior member of the IEEE and served as the Syracuse MTT/AP Chapter Chairman from 1985-1986 and from 2012-2013. He is currently Treasurer and Administrative Committee member for the IEEE Antennas and Propagation Society. He is a registered Professional Engineer in New York State
