Operation
The basic principle of operation consists of detecting the frequency shift between a transmitted and a
received signal reflected back from a moving object within the field of view of the unit.
The unit produces a low level IF output signal which can be amplified and processed to provide an
audible or visual alarm signal and employs low cost surface mount manufacturing techniques which
are field proven as being rugged and reliable.

NOTES
Detection range is dependent on size and reflectivity of target and
S/N ratio Doppler shift at 10.525GHz is 31Hz/m.p.h. Unit functions
over -30ºC to +70ºC but performance may be degraded above
+55C.
