Method of calibrating modulation meter MI 2305
Vojnotehnički Glasnik, 2000 In this article an original way of calibrating the MI 2305 modulation meter is described. AM traceability is achieved using tree secondary etalons. FM traceability calibrating is achieved by using the Bessel zero method.

Comparative Analysis of Mathematical Models of Tracking Radio Altimeters
Известия высших учебных заведений России: Радиоэлектроника, 2022 Introduction. Tracking radio altimeters of low altitudes are widely used in civil aviation. These devises use periodic frequency modulated continuous wave (FMCW) signals, while altitude measurements are based on processing the beat signal processing. For
