Identify the different parts of the radar sensor ORION

It is very important you are able to identify the basic parts of the radar in order to avoid wrong set ups of measurement.

The next picture show which is the 24GHz transmitting antenna, the receiving antenna, the transmitter (TX) and the receiver (RX):

You can also take a look at the bottom face:

JL1 gives you access to the VCO signal

JD1 is the modulation signal

JD2 is the synchronism (you can use this signal to visualise the others on an oscilloscope)

JF1 is the IF signal

JC2 is the expansion connector for IGEPv2

JC4 and JC3 are the expansion connectors for IGEP COM MODULE

JP1 is the power connector

Expansion connector

Expansion connector JC1 is intended for control and monitoring of internal radar sensor ORION signals.

o   (2):        INPUT when power supply is applied to radar board. OUTPUT in other case.

IGEPv2 Expansion

A single expansion connector, JC2, is enough to adapt IGEPv2 processor board to the radar sensor ORION.

IGEP COM MODULE Expansion

2 expansion connectors are needed to interface radar sensor ORION with processor board IGEP COM MODULE: JC3 & JC4

JC3 pin-out
