Frequency modulated continuous wave radar modeling for landslide detection in Malaysia

Abstract

Landslide is one of natural hazards that is frequently happen after continuous heavy rainfall especially during monsoon season. It effects serious damages on property and also treat human being’s live. The objective of this paper is to design and evaluate the performance of a Frequency Modulated Continuous Wave (FMCW) radar for detecting of slow moving landslide movements in Malaysia. The performance of the proposed radar design is tested by using Agilent Advanced Design System (ADS) software. It operates at 2.4 GHz carrier frequency with a resolution range of 0.75 m. Its signal power increases around 38 dBm after de-ramping process. Hence, it increases the sensitivity of the radar to detect the landslide occurrences. The radar has capability to detect landslide movements of 20 m/s speed.
