Torry Akins

Torry Akins is a Senior Hardware Engineer at Remote Sensing Solutions, Inc. He received both his M.S. and B.S. degrees in Electrical Engineering from the University of Kansas.

Since joining RSS, Mr. Akins has developed a 1 GHz Direct Digital Synthesizer (DDS) module and a 3.6 GHz 12 bit data acquisition module. The DDS module supports the generation of multiple linear chirps and/or pulses.Additionally, it supports the application of arbitrary amplitude tapers to its output waveforms. The data acquisition modules can directly capture high bandwidth radar returns. These data are buffered and transferred over a high speed serial link to RSS's digital receiver. Multiple data acquisition modules can be synchronized to capture the return from a multichannel radar system.

Prior to joining RSS, Mr. Akins worked in the Aviation Department at Garmin International where he led the development of several of Garmin's transponder products. Before that, he was at the University of Kansas where he worked as a staff engineer at the Center for the Remote Sensing of Ice Sheets (CReSIS). During that time, he developed the waveform generators and data acquisition systems for several airborne and ground based radar systems.
