Masters thesis presentation
Microwave Radar Implementation in Outdoor Home Alarm Systems
Isabelle Larsson
Gustaf von Plomgren
The use of short range microwave radars for motion sensing purposes are on
the rise in multiple industries, as they are accurate, small in size and
relatively cheap. The automotive industry, in particular, has pushed the
development forward. Lately, the home alarm industry has also been glancing
at the technology. Radars are well suited for outdoor applications as they
are insensitive to precipitation, fog and hot weather that has an impact on
the performance of the more common sensors used for intrusion detection:
cameras and passive infrared (PIR) sensors.
This report investigates how a microwave radar can be implemented as a
motion sensing detector in a battery powered outdoor alarm device. Two
microwave radars are evaluated before one is chosen for further testing. The
experiments are conducted with a focus on the performance of the radar
compared to the PIR, as well as the radar's adequacy in an outdoor
environment.
The final result is a prototype containing a PIR sensor and a camera
together with a 24 GHz radar as a secondary sensor. Even though the radar
outperforms the PIR, it is too power consuming to be implemented as the
primary sensor of a battery driven device. The report concludes that low
cost, low power radar sensor may very well be a part of the next generation
home alarms.
