Latest Patents

Collins holds a patent for a system titled "Terrain Aided Passive Range Estimation." This invention employs a passive ranging extended Kalman filter to accurately locate ground-based targets using platform-referenced passive sensors. The system integrates angular target measurements, such as azimuth and elevation, from various sensors, including FLIR and RFR, along with stored digital terrain data. The Kalman filter algorithm effectively fuses these inputs to provide recursive least-square error estimates of target location. An iterative algorithm calculates the slant range to the intersection of the target's line of sight vector with the digital terrain database. This calculated slant range is then used as an input to the Kalman filter, complementing the measured azimuth and elevation inputs. The system is designed to deliver rapid solutions by leveraging stored digital terrain data for range estimates. The Kalman filter framework also facilitates fusion, measurement noise filtering, and automatic triangulation when the owncraft maneuvers enhance observability. Results from a Monte Carlo simulation of the algorithm, utilizing real terrain data, demonstrate the system's effectiveness. The analysis includes measurement noise effects and the more dominant terrain effects on estimation accuracy.
