Modeling of the methodical errors of high-precision aircraft radar altimeter operating above the sea surface at low altitudes

摘要

The paper presents a developed algorithm for calculation of methodical errors of estimation of the height of flight of the aircraft at low altitude in relation to the model of the sea surface, described by conventional spectral functions of sea waves. The problem of describing the irregular sea surface is solved using the principle of superposition - the overlay of simple harmonic waves.
