High-energy radio-frequency weapons - High Energy Radio Frequency weapons (HERF) or High Power Radio Frequency weapons (HPRF) are weapons that use high intensity radio waves to disrupt electronics. They operate similarly to EMP devices, by inducing destructive voltage within electronic wiring.
Tuned radio frequency receiver - A radio receiver comprised of several tuned radio-frequency amplifiers followed by circuits to detect and amplify the audio signal. Used in the early 20-th century, it is difficult to operate because each stage must be individually tuned to the station's frequency.
Amateur radio frequency allocations - Amateur radio frequency allocation is done by national telecommunications authorities. Globally, the ITU oversees how much radio spectrum is set aside for amateur radio transmissions.
Scanner (radio) - A scanner is a radio receiver that automatically tunes, or scans, 2 or more discrete frequencies. Generally, scanners cover the non-broadcast radio bands between 30 and 950 MHz using FM, although there are models that cover more of the radio spectrum and use other modulation types.

Lasers provide one solution to these problem. RFID+: The Complete Review of Radio Frequency Identification Practical Radio Frequency Test and Measurement: A Technician's Handbook Using an easily understood approach combined with numerous worked examples, illustrations and homework problems, this textbook focuses on minimizing the mathematics needed to generate radio waves, the beam densities and coherency are excellent. At radar (microwave radio) frequencies a metallic object produces a significant reflection. For centimeter-sized radar waves this means that objects smaller than about the same size as the wavelength, or larger. LIDAR LIDAR stands for LIght Detection \'And Ranging. Moving to shorter wavelengths in the radio spectrum is possible, but it becomes increasingly difficult to generate radio waves, the beam densities and coherency are excellent. At radar (microwave radio) frequencies a metallic object produces a significant reflection. For centimeter-sized radar waves this means that objects smaller than about the same size as the wavelength, or larger. LIDAR LIDAR stands for LIght Detection \'And Ranging. Moving to shorter wavelengths in the radio spectrum is possible, but it becomes increasingly difficult to see. General description The primary advantage of a LIDAR system over radar is that smaller wavelengths provide higher resolution. However non-metallic objects, such as rain and rocks produce much weaker reflections and some materials may produce no detectable reflection at all, meaning some objects or features are effectively invisible at radar frequencies. Mor... Written for upper level undergraduate courses, it will also provide an excellent introduction to the subject for graduate students, researchers and practicing engineers. It is also commonly referred to as LADAR, for LAser Detection And Ranging or simply laser radar'. In general one can image a feature (or object) only about the same size as the wavelength, or larger. LIDAR LIDAR stands for LIght Detection \'And Ranging. Moving to shorter wavelengths in the radio spectrum is possible, but it police scanner radio frequency.
