Numerous aircraft accidents have occured during takeoff and landing due to the strong and unexpected winds diverging from a microburst outflow. extensive research has indicatedthat it is possible to detect such winds by means of a doppler weather radar. a logical radar candidate is the unit carried… More

Designing and testing surface search radars for detecting small targets on sea clutter requires knowledge of the magnitude and time varying nature of the radar cross section (rcs) of both the target and the sea clutter. a major factor in establishing clutter and target rcs is the multipath… More

Seaborne powered targets are currently remotely controlled via line of sight radio frequency systems. it is desired to remove this line of sight limitation. the proposed solution will utilize a target borne loran c navigator to establish location and autonomously control the target between waypoints… More

GPS receivers are heavily used in aviation for both visual and instrument flights. There is a need for a backup system so that enroute and non-precision approaches can be flown without reliance on ground based systems should GPS be unavailable. We propose to use barometric pressure, airspeed,… More
