As each portion of the wavefront reaches the reflecting surface, it is shifted by 180 degrees, the phase angle and in all sections of the field will be sent out in the parallel paths of travel.
THIS IS AN IDEALIZED RADAR and produces a pencil beam. If the reflector has an elliptical shape, then it will produce a fan-shaped beam.
