摘要： Systems and methods for providing passive bird-strike avoidance. A passive L-band receiver system is located on an aircraft. The system includes a processor and an antenna having an array of four or more elements. The antenna configured to receive L-band signals. The processor receives the L-band signals from the antenna, determines if the received L-band signals indicate a target, determines distance, direction of travel and speed of any determined targets, determines if the target is a flock of birds based on the determined speed and determines if a hazard condition exists based on the distance, direction and speed.

摘要： A method and apparatus selects the minimum value of a sequence of power measurements taken from each range of a radar's target area. This is preferably performed for two channels of a radar, and the minimum values of both channels for each range are compared to determine the likelihood of a target in each range. Once such likelihood is established, then further processing takes place with regard to ranges with high likelihoods of having targets. The determined minimum value for each range may also be used to normalize each range's power measurements, while preserving phase information, for moving target detection.

摘要： A method for radar aided positioning of an air vehicle for approach and landing is described. The method includes integrating global navigation satellite system (GNSS) data and inertial data to calculate a position of the air vehicle, scanning the environment forward of the air vehicle with a radar, and accessing a database of terrain features and their radar signatures. The method further includes matching features in the radar scan data to the radar signatures in the database to determine an actual position of the air vehicle and synthesizing glide slope and localizer signals for the approach and landing based on the determined actual position.

摘要： Methods and apparatus for determining an altitude with an altimeter is provided. One method includes transmitting a signal having a fixed modulation period towards a ground target and then detecting reflected signals off the ground target. The method then implements a single Fast Fourier Transform (FFT) on the detected signals for each modulation period that computes all possible altitudes in real time. A short history of the real time altitude calculations is collected and then the altitude based on the short history of the real time altitude calculations is determined.
