Respond to the call of ham radio
Despite its old-school reputation, amateur radio is on the rise, and the airwaves are busier than ever. That’s no surprise: being a ham is a lot of fun, providing an independent way to keep in touch with friends, family, and new acquaintances around the world?and even beyond with its ability to connect with the International Space Station! Hams are also good in a crisis, keeping communications alive and crackling during extreme weather events and loss of communications until regular systems like cell phones and the internet are restored. Additionally, it’s enjoyable for good, old-fashioned tech geek reasons?fiddling with circuits and bouncing signals off the ionosphere just happens to give a lot of us a buzz!

Design, simulate, and deploy UAV applications. UAV Toolbox provides tools and reference applications for designing, simulating, testing, and deploying unmanned aerial vehicle (UAV) and drone applications. You can design autonomous flight algorithms, UAV missions, and flight controllers. The Flight Log Analyzer app lets you interactively analyze 3D flight paths, telemetry information, and sensor readings from common flight log formats. For desktop simulation and hardware-in-the-loop (HIL) testing of autonomous flight algorithms and flight controllers, you can generate and simulate UAV scenarios. You can simulate camera, lidar, IMU, and GPS sensor outputs in a photorealistic 3D environment or in a 2.5D simulation environment.

This second edition introduces the theory and applications of the modulation transfer function (MTF), used to specify the image quality achieved by an imaging system. It starts with the relationship between impulse response and transfer function, and the implications of a convolutional representation of the imaging process. Optical systems are considered first, including effects of diffraction and aberrations on the image, with attention to aperture and field dependences.
