Topic: Sonar Concepts

Due: Monday, February 5

1. As was done in class, draw a diagram showing the response of an ideal sonar, whose beam width is alpha, to the following objects:
    
   1. A box whose front side is perpendicular to the sonar beam, and which covers beta < alpha of the beam.
       
   2. A box whose front side is perpendicular to the sonar beam, and which covers beta > alpha of the beam.
       
   3. A square box whose diagonal is perpendicular to the sonar beam, and which covers beta < alpha of the beam.
       
   4. A square box whose diagonal is perpendicular to the sonar beam, and which covers beta > alpha of the beam.
       
   5. An infinitely long "inside corner" of a room.
       

   In all cases (especially the last one), you can assume that there are no reflections.
