This book was released on 2018-09-29 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: SONAR (sound navigation and ranging) systems have many similarities to RADAR and electro-optical systems. Again, detection is based on the propagation of waves between the target and detector. There are active sonar systems, where the wave propagates from the transmitter to the target and back to the receiver, analogous to pulse-echo radar. There are also passive sonar systems, where the target is the source of the energy which propagates to the receiver, analogous to passive infrared detection. Therefore, a great deal of what has been discussed about these systems will also apply to sonar. Sonar, however, differs fundamentally from radar and electro-optics because the energy is transferred by acoustics waves propagating in water. So we first begin by discussing the characteristics of acoustic waves.

Book excerpt: A New York Times Bestseller! We know there are certain things we must have to survive--food, shelter, and safety to name a few. But there are also aspects of life that truly allow us to be joyful and fulfilled. For popular podcaster and bestselling author Annie F. Downs, fun is close to the top of that list. Few would argue that having fun doesn't enrich our lives, but so much gets in the way of prioritizing it. Tough days, busyness, and feelings that are hard to talk about keep us from the fun that's out there waiting to be found. With That Sounds Fun, Annie offers an irresistible invitation to understand the meaning of fun, to embrace it and chase it, and to figure out what, exactly, sounds fun to you--then do it! Exploring some research and sharing some thoughts behind why fun matters, she shows you how to find, experience, and multiply your fun. With her signature storytelling style and whimsical vulnerability, Annie is the friend we all need to guide us back to staying true to ourselves and finding the fun we need.
