The observation of agricultural crop conditions through satellite platforms has been of vital importance for the development of decision making systems in the field Passive sensors determine land surface conditions by measuring the reflectance of solar radiation, while radar satellites emit their own radiation Active satellites can acquire information even under cloudy conditions, unlike passive satellites, which lose functionality The purpose of this work is to study the use of both types of satellites for analyzing vegetation cover in citrus crops and to evaluate the possibility of replacing passive sensor data with active data, along with training recurrent neural networks, particularly Long Short Term Memory (
