4ward Sciences Systems Engineer and Scientist: Lloyd Salsman

I attended Oklahoma State University, where I earned both my BS and MS in Electrical Engineering in the early ‘70s. I have worked for several technology companies since.

My experience has been technical in nature on a wide variety of sensors, communications, and embedded data processing programs. My responsibilities have included program and project management, systems engineering, design, algorithm development, evaluation of prototype designs, coding, laboratory and field testing. I enjoy being the systems architect while keeping my sleeves rolled up through integration and deployment. I have worked on a variety of projects.

To list a few:

National Airways Systems Engineering:
I worked with the FAA on their radars, communications, navigation, and environment control systems which support commercial and military aviation over the USA.

Detection Systems:
I have participated in signal processing projects involving small FMCW radars for personnel, animal, and vehicle detection. Currently, I am converting a 35 GHz animal detection system research prototype to a production unit. The system has been under development and testing for two years in Yellowstone National Park. Data collected from these systems has been used to characterize MMW propagation and interference effects of vehicles and animals along an active highway corridor. Control and monitoring of a remote system is accomplished by Low Earth Orbiting Satellite (LEOS) data service.

Highway Messaging System:
I was a principal engineer building a system for communicating and coordinating highway messaging signals using ground and satellite radio communications has been developed. Using a web portal, traffic control operators can rapidly post messages on multiple signs. This system implements the “Amber Alert” network in South Carolina and is spreading to other states.

Chemical Sensing:
I have developed a system for rapid chemical sensing and speciation based on the response of a coated piezoelectric crystal. My technique allows rapid scanning of an array of crystals for quantitative as well as qualitative determination of chemical contaminants. This technique has been demonstrated in the field at the Savannah River Site near Aiken, SC in 100 meter monitoring wells.

Seeker Systems:
I developed a seeker system for a Sparrow-based (AIM-7) anti-radiation missile (ARM). This system used a fully-digitized microwave receiver, signal sorting engine, automatic threat matching/selection, and tracking. The system contained three microcomputers including a specialized, micro-programmed digital signal processor. The seeker design evolved through several receiver iterations ending with a Sidewinder-based (AIM-9) system employing phase/amplitude comparison mono-pulse direction finding and the ability to characterize complex pulse modulation schemes.

I have a First Class Radiotelephone License (now Commercial License) issued by the FCC. I am also a licensed amateur radio operator.
