DAB-602

Bistatic or Monostatic?

In Ground Penetrating Radar the terms "Monostatic" and "Bistatic" are use quite freely. Many times when experts talk about antennas operating in monostatic mode, in the reality they mean bistatic mode but with the transmit and receive channels very close to one another.

However, strictly speaking in monostatic operation a common antenna is used for both transmitting and receiving. While in bistatic operation, the transmitting and receiving antennas are different and might be placed at a considerable distance from one another. Any antenna that accepts plug-ins like the TR501 transceiver or in the lack of it a 769DA2 transceiver, can be operated in monostatic mode.

Is it any use of operating the antennas in bistatic mode?

What can be done in bistatic mode that cannot be done in monostatic mode? Common Mid Point (CMP) measurements, Wide-Angle Reflection and Refraction (WARR) test and Transilumination measurements are possible only in bistatic mode. All of which are direct wave measurements and they provide information about electromagnetic wave velocity in the media and sometimes are used for creating 3D radargram structures.

It is possible to use two identical antennas with a two channel radar for performing measurements in bistatic mode. On the other hand if you have a single channel radar like the SIR-3000, then bistatic mode is not possible unless you have an antenna channel splitter like our DAB-601 or DAB-602

DAB-601 or DAB-602? That's the question.

The DAB-602 should be used instead of the DAB-601 when:

You need to switch or "swap" the transmitter and receiver on the antennas, or
You need to select monostatic or bistatic mode without deataching antennas
Don't need an input for the marker button since it is used for the toggling control
Don't need automatic control.

The DAB-602 as the DAB-601 is safe, easy to operate, RoHS compliant and EMC compliant.
