How to identify multiple objects in a sphere cast?

Hi, I am trying to implement a RADAR sensor in unity. I am currently using sphere cast to identify the object and measure its velocity and distance. At the moment even though there are several objects in within the radius of the sphere cast ,It only identifies the nearest one. How can i make it recognize all the objects within the sphere cast.?

Any help would be appriciated…

Use Physics.SphereCastAll which will return a RayCastHit[] instead of a single RayCastHit
