Abstract


The crop growth status acquired through remote sensing can deliver a reference for the establishment of
agricultural product regulation and control policies. Synthetic aperture radar systems are active remote sensing systems
sovereign of weather and sun illumination. This paper presents an overview of the systematic summary of the recent
developments of SAR remote sensing for agricultural applications and analyses the problems and future development
trends. Optical remote sensing methods for studying crop growth status and yield are usually characterized by a grouping
of different features that are used to build contacts with the crop bio-physical or eco-physiological parameters, such as
chlorophyll content, leaf area index, biomass or plant water content. Synthetic aperture radar has a relevant advantage
over optical sensors for it can obtain data in scanty weather conditions; so, it has special value in the area of agricultural
remote sensing.  In this paper, we arranged synthetic aperture radar agriculture practice into three main categories: crop
biomass valuation, cropland parameter evaluation, crop capacity estimation methods based on synthetic aperture radar
data assimilation.
