Venus has a dense cloud layer, so regular light doesn't get through.
Radar could get through and give an image of the Surface.
The planet Venus was imaged using radar because its thick atmosphere makes it difficult to observe the surface using optical telescopes. Radar can penetrate the clouds and provide detailed images of the planet's surface features. Additionally, radar can also measure the surface elevation and map the topography of Venus.

Venus is not orange. The orange/yellow image you see is a false-color radar imaged used to map the surface. Due to the thick deck of clouds, Venus actually appears off-white from space.
Doppler radar can measure wind speeds in a storm. In the eye of a hurricane the radar would register low winds, thus indicating calm conditions.

It provides a 3 dimensional image. Older radar shows a 2 dimensional image.

To make the aircraft very difficult to detect on radar. It has about the same image on radar as a hummingbird.

A Periscope or Radar
Having a radar detector will alert you when a Police Car with its speed radar is near. The Radar Detectors will produce an audible signal alerting you of this, and will do so far in advance of when you are able to see the Police Car.

Hook echoes in a radar image are a sign of possible tornadoes.
