Radio Wave Direction/Deviation Determination Systems TRIZ Cases
- NVIS Emitter Localization Using Multi-Site Elevation Angles
Weak groundwave signals are avoided by converting multi-site NVIS elevation angles into overlapping location areas for more accurate emitter finding.
- 3D Pointing Control Target Selection for Smart Device Networks
A mobile device and gateway use 3D location and pointing direction to identify the intended smart device with fewer control steps.
- Angle-Based Target Tracking With Multi-Hypothesis Kalman Filters
Classify stationary, moving surface, and airborne targets from angle-only signals using SSF, MSF, and pseudorange Kalman filters.
