The Inside Story on Software RadioAerospace & Defense Technology interviews Rodger Hosking, Vice President, Pentek
Software radio technology now pervades an extensive range of mil-aero applications including radar, EW, communications, SIGINT, ELINT, countermeasures, weapons, missiles, monitoring, navigation, and tracking.
A&DT: What is software radio and how did it get started?
Hosking: Two critical technologies started to evolve rapidly in the 1970s. The first is data conversion technology that gave us ADCs (analog-to-digital converters) and DACs (digital-to-analog converters). The second is digital signal processing device technology that gave us DSP hardware chips. These enhanced microprocessors have dedicated multipliers, look-up tables, arithmetic units and memories to perform the necessary operations on sampled signals to and from DACs and ADCs at a given sample rate. Since these operations are controlled by software programs, once these DSPs and data converters were fast enough to convert and process radio frequency signals, the term "software defined radio" (or now simply "software radio") was coined.
Model 6001 8-Channel A/D & D/A Zynq UltraScale+ RFSoC Processor - QuartzXM
The VITA Standards Organization (VSO) has started a "VITA Personas" segment on their website to highlight some of the people who contribute to shaping VITA standards.
The VSO recently featured Paul Mesibov, co-founder and Chief Technical Officer at Pentek, as one of their VITA Personas. What follows is taken from the VSO's profile of Paul.
Paul Mesibov has over 35 years experience in the electronics industry and oversees the design and implementation of Pentek's digital signal processing, software radio, and data acquisition products. He is currently an active member of SOSA, PICMIG, VITA, PCI-SIG, and IEEE, as well as a key contributor to several ANSI standards.
