Geolocation is the process of calculating a signal’s position on the surface
of the earth. This process can be performed by computing the direction
of arrival (DoA) from two or more independent, known locations, and
observing where these directions cross. This “triangulation” can be
done from multiple stationary platforms or by performing multiple DoAs from
a moving platform. On Target Enterprises extends the direction of
arrival research to geolocation methods, using classical and hybrid DF
methods.
- Application of geometric rate-of-change to estimation of source
position
- Typically uses hybrid direction finding methods in conjunction with
time/position estimation
- Military applications
- Commercial utility
- Communication interference mitigation
Many of the applications for this research are of a military
nature, typically for situational awareness, crisis area monitoring, and
early detection of potential problems. Emerging commercial
applications include identification and geolocation of signals that
interfere with communication systems. This allows economic and
political opportunities to be explored where technical efforts may be
cost-prohibitive.
