Navigation Sensor Accuracy Requirements for Emerging Laser Radar Applications
Abstract
This paper draws attention to the emerging military capabilities of laser radar by describing state-of-the-art technology for applications involving helicopter obstacle warning, automatic target identification at far range, and automatic target detection and classification at close range. In all applications sensor processing requires accurate motion compensation using navigation data; the accuracy of the navigation sensor needed depends on the application and the laser radar being used. This paper analyzes how navigation and sensor errors affect sensor processing results, specifies maximal velocity and angular velocity errors of the navigation system, and examines to what extent an inertial navigation system with low-cost micromachined gyros and accelerometers can be expected to meet these specifications.
