Abstract

The main topic of this paper is a radar ranging for use in an aircraft altitude measurement. This should help beginner pilots in practicing landing and take off.  To achieve this aim, we chose to use continuous-wave radars with frequency modulation (FMCW). Our solution is based on linear frequency modulation method using triangular modulation pattern.  During the testing, it was found out, that radars with 24 GHz bandwidth have a range resolution from 1 meter (depending on modulation depth) to 13 metres. This range is sufficient for usage in training of takeoffs and landings, which is the real purpose of this paper. Another good finding is, that during takeoff and landing, there is minimal occurrence of doppler frequencies.  Final algorithm works on principle of two currently processed spectrums, which are substracted. Afterwards, found peaks are validated on current spectrum.
