When considering a sonar product for use in navigation, it is important to consider a number of parameters and system characteristics. Obviously, the ability to look ahead is important. However, "where", "how", and "when" the sonar looks ahead are characteristics that will determine if a particular sonar is suitable for navigation and practical obstacle avoidance. A sonar's overall system design impacts these characteristics significantly. Scanning sonars are one of the most common system designs for advanced sonar solutions as they are relatively inexpensive and relatively small. This makes them a good solution for many applications. Unfortunately, real-time navigation is not one of them. This blog post illustrates the advantage of phased array processing sonars over scanning sonars for navigation applications.
