Concealment and weather can make some objects elusive. This calls for a new type of data collection. Satellite-based radiofrequency (RF) scanning can be used to discover and pin-point the “needle in the haystack”.
Defense-grade detection
Electronic signals intelligence (ELINT) refers to the ability to geolocate the sources of signal emissions in a given area.
Satellite-based RF detection is the next generation of ELINT capability, now commercially available.
RF detection capabilities on demand
When compared to other means of satellite sensing, radiofrequency detection stands out in a number of ways. One could draw a comparison to human senses: if optical sensors are “vision”, then radiofrequency sensors would be “hearing”.
Various types of machinery emit radio signals, whether it is for radio communication, navigation or detection (via radar). An example would be commercial ships which use radar for collision avoidance and bearing. Mobile ground-based radars also emit strong signals, used to discover and track aerial objects.
By scanning the radio waves, sources of radio emissions can be discovered and geolocated. Every satellite operator has a distinctive approach to building this sophisticated data capability – and many of these capabilities are now commercially available.
Maritime
Detecting RF sources at sea can be crucial for dark ship tracking and interception, helping prevent illicit trade, marine poaching, wildlife habitat destruction, and piracy, as well as other threats to shipping.
Land
Land-based sources of RF emissions notably include emergency beacons, air detection radars and communication devices. Mapping their locations can provide critical information.
