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.

摘要： The present invention provides a radar altimeter system with a closed loop modulation for generating more accurate radar altimeter values. The system includes an antenna, a circulator, a receiver, and a transmitter. The circulator receives or sends a radar signal from/to the antenna. The receiver receives the received radar signal via the circulator. The transmitter generates a radar signal and includes a phase-locked loop circuit for generating the radar signal based on a pre-defined phase signal. The transmitter includes a direct digital synthesizer that generates the phase signal based on a pre-defined clock signal and a control signal. The system includes a digital signal processor and a tail strike warning processor that determine position of a tail of the aircraft relative to ground and present an alert if a warning condition exists based on the determined position of the tail of the aircraft and a predefined threshold.
