Development of a Cheap Helicopter Assisted Landing System Method

Deniss Brodņevs, Igors Smirnovs

Abstract


This paper presents a relatively cheap helicopter assisted landing system concept. A frequency modulated continuous radar (FMCWR) is used to check an unprepared landing area for the presence of interfering objects. The spectrum processing of the converted signal is used to provide multi target resolution. The experimental research is done by using a 4.3 GHz FMCWR radar. The converted signal spectra are provided for mirror and rough surfaces, as well for multiple targets in a case of interfering object existence.

Keywords:
Diffusive reflection; frequency modulated continuous wave radar (FMCWR); mirror reflection; multiple target resolution; rough reflective surface; smooth reflective surface; spectral processing
