BASIC OPERATION
IGEP
™
RADAR SENSOR ORION can be operated by supplying +5Vdc to JP1 connector and
programming the DDS Modulator through SPI link available whether on JC2 or JC3 connectors.
IF signal can be obtained also on any of both connectors and you can also get sampled data of
this IF signal through the same SPI interface as the one used to program DDS Modulator.

RADAR ARCHI
The VCO included on the transmitter generates a Radiofrequency carrier in the vicinity of
12GHz. This frequency can be controlled and modulated by applying the correct voltage to the
input of the VCO (accessible only on demand). The generated signal is then frequency doubled,
thus generating a signal in the vicinity of 24GHz (World-Wide ISM Band covered). This signal is
then transmitted by the antenna and a part of it is used as Local Oscillator on the receiving
mixer (MIX). The low level reflected waves captured by the receiving antenna are fed to the
LNA and once amplified they are mixed with the local oscillator signal. The mixer output will be
a signal with a frequency that is the difference between the respective frequencies of the
received and transmitted signals. This IF signal is then amplified. From this IF signal it can be
obtained information about the speed and/or position of different targets, by applying the
adequate modulations and processing algorithms.

RADAR PRECAUTIONS
Please be aware that any manipulation to the shielding and the micro-strip circuit
can reduce
drastically the Radar performance
due to the high sensitivity of this kind of circuits. A part of
our design success is the perfect matching shielding done in our factory. Warranty will be lost
if this area has been manipulated.
Different radar applications need different antenna patterns
and characteristics, and the
performance is highly dependent on the used antenna. If you need other antenna
characteristics please contact Radar Support and we will study the possibility to implement a
personalized development:
