It is not always easy or possible to use active radars and install a transmitter due for example to potential interference with existing systems (i.e. in case of an airport).
MetaSensing complements its offer by means of a passive radar.
This kind of radar has the big advantage of being completely passive, usually exploiting commercial broadcast signals as DVB-T transmitters that typically exist in any urban environment.

The main advantages of this radar are:
-
Low cost (no transmitter)
-
Easy to deploy
-
Compact;
-
Low power;
-
-
Compact
-
DVB-T frequency permits a compact antenna
-
-
Typical Radar Advantages
-
All weather;
-
Night & Day

The system is built upon the latest architectural concepts and Signal Processing techniques. Its compact antenna is a circular array enabling advanced spatial filtering for adaptive cancellation of clutter and reference.
The system can perform also Passive Coherent Location.
