Hi all, I am starting an internship with Lockheed Martin on Tuesday, May 26. I have just been notified of my duties, which will involve resolving issues with hydrophones/transducers. I am looking for recommendations of good textbooks that I could refer to during this internship. I am a rising senior in the Aerospace Engineering program at Virginia Tech, as an AE student I have less electronic experience than students in ME or EE (obviously). I am, however, very confident in my ability to self-learn and I really want to perform this summer as Lockheed Martin is a dream company for me. Thanks in advance for any and all recommendations.
