Radar-processing algorithm of harmonic frequency modulated low-altitude altimeter

Keywords:

S. V. Porshnev


In the article processing algorithm of the FM-Altimeter is described. In contrast to the classical algorithm which is based on calculation of the signal's zero crossings' number, the described algorithm is free from its most essential shortcoming, the discrete error depending on – frequency deviation of sounding EV. Functionality of this algorithm is shown using the example of the signal output of FM-Altimeter with harmonical modulation law.
