The project
Our communications electronics core area has some interesting applications. We have been involved in applying communications theory and signal processing methods to augment a design team working on ionising radiation detection equipment, focusing on methods to identify and discriminate particular types of radiation. Key skills we supplied in this area were:
- Signal detection analysis and design
- Embedded software design
- Low noise RF circuit design
- Technology transfer between industry sectors

About our client
Symetrica specialises in the detection and identification of radioisotopes for Security Applications. They work with prime contractors and government agencies to design, develop, test and deploy detection equipment for use by law enforcement personnel, customs officers, the emergency services, military personnel and first responders.

“ASH are a small, very responsive, electronics/firmware development company who rapidly produced an initial prototype circuit board within days of being briefed about our urgent needs... Since that initial contact with ASH, we have used their design and prototype assembly skills on several occasions to provide support to our R&D team.
ASH have provided Symetrica with a very valuable service at a time when our electronics design and construction resources were overstretched. I have no criticism of the support that ASH have provided during the past two years.”
