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. This produces a low level output signal that

can be amplified and processed.

The tunable transceiver incorporates provision for electronically tuning the unit over a frequency range of approximately

5MHz. This enables frequency modulation to be applied to the transceiver or fsk ranging to be performed.

The unit employs low cost surface mount manufacturing techniques that are field proven as being rugged and reliable.

Notes:

Detection range is dependent on size and reflectivity of target

and S/N ration.

Doppler shift at 10.525 GHz is 31Hz/m.p.h.

Unit functions over -30ºC to +70ºC but harmonics

may exceed specified levels.
