Experimental Results for GNSS-R based Moving Target Indication

Global Navigation Satellite System Reflectometry (GNSS-R) is becoming a research hotspot in the remote sensing areas recently. This paper is focused on a new application of GNSS-R: Moving Target Indication (MTI). A modified GNSS-R based MTI algorithm is proposed. By the adding of a Doppler Frequency Modulation Rate (DFMR) estimation step, the modified algorithm could significantly improve the Signal to Noise Radio (SNR) of the target. An experiment is conducted for validation and the proposed algorithm performs well.
