    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: L'invention concerne un procédé de construction de systèmes micro-ondes et de traitement du signal par corrélation. Elle trouvera notamment son application en cinémométrie, télémétrie, asservissement de direction et de poursuite, détection d'hétérogénéité et de discontinuité dans un matériau à partir de capteurs fonctionnant au contact ou sans contact.
    Selon le procédé de l'invention, qui utilise le rayonnement micro-onde, des antennes de réception des micro-ondes et au moins un corrélateur, on réalise au moins les étapes suivantes:

    - on émet un rayonnement micro-onde (1) unique à l'aide d'une source micro-onde (2) dont les caractéristiques sont déterminées et d'une antenne d'émission A,
    - on capte à l'aide d'antennes de réception A1, A2 situées en différents points, le rayonnement micro-onde émis,
    - on dirige les signaux perçus par les antenes de réception A1 et A2 vers un ou plusieurs corrélateurs (3),
    - on analyse le spectre de fréquence du signal de sortie du ou des corrélateurs.

    Selon l'invention, l'analyse du spectre de fréquence du signal de sortie s'effectue par transformée de Fourier (FFT) ou par tout dispositif permettant d'extraire le fondamental du signal de sortie ou de mesurer l'intervalle de temps séparant deux passages au zéro du dit signal de sortie.

    摘要: A measuring apparatus is provided in one of two objects moving relatively to each other. The apparatus includes a circuit (18, 20) for effecting a direct spread modulation with respect to a transmission carrier signal (f₀) using modulation codes (MA1, MB1); an antenna unit (22, 24) for transmitting the modulated carrier signal toward the other of the two objects and for receiving a reflection wave therefrom; a circuit (30, 32) for demodulating the received reflection wave signal using the transmission carrier signal; a circuit (42, 44) for making correlation between the demodulated output signal (IF1, IF2) and a signal (MA2, MB2) having the same code as that of the modulation code and having a phase delayed by a predetermined time; a unit (46, 48) for extracting a Doppler frequency component contained in a signal which has been propagated through a propagation path existing in a specified distance range; and a circuit (60) for properly processing the extracted Doppler frequency component. By the constitution, it is possible to precisely measure a speed and/or direction angle of one object relative to the other of the two objects, without being subject to an influence by a reflection in the close neighborhood, or an influence by interference of a transmission signal or interference signal in a receiving channel of the apparatus.
