Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.

Active remote sensing uses its own energy source to illuminate the target and measure the reflected signals, such as radar. Passive remote sensing relies on external energy sources, like the sun, and measures the natural radiation emitted or reflected by the target, such as with optical sensors.

A microwave camera on a remote-sensing satellite can capture data by detecting microwave radiation emitted or reflected from the Earth's surface and atmosphere. This technology is particularly useful for monitoring weather patterns, soil moisture, and vegetation health, as microwaves can penetrate clouds and work in various weather conditions. By analyzing the microwave signals, scientists can gather valuable information about temperature, humidity, and surface characteristics, aiding in climate studies and disaster management. Additionally, this capability enhances our understanding of natural phenomena and supports agricultural planning and monitoring.
