摘要： A method and system for estimating velocity of an aircraft is provided. The method comprises transmitting a beam toward a surface from the aircraft using a Doppler beam sharpened radar altimeter, receiving a plurality of reflected signals that correspond to portions of the transmitted beam that are reflected by the surface, and forming a plurality of Doppler beams by filtering the received signals. A complex-valued array of range bin is computed with respect to frequency of the Doppler beams from at least one antenna aperture of the radar altimeter, and a range for each of the Doppler beams is estimated. A velocity vector magnitude for the aircraft is estimated by a curve fit of the range with respect to the frequency of the Doppler beams.

摘要： Apparatus and methods of determining altitude information with a radar receiver with quadrature detection is provided. A method includes generating baseband frames. An oscillator signal is created within each of the baseband frames. A return of the oscillator signal is coupled to a first input of a mixer. Moreover, the oscillator signal is coupled to a second input of the mixer. A phase of the oscillator signal is selectively changed between two or more distinct values. Timing of the change being based at least in part on a baseband frame timing of the generated baseband frames. Samples of an output of the mixer are selectively collected further based at least in part on the baseband frame timing. The collected samples are processed to compute altitude information.
