RF weapons are usually divided into two categories: high power microwave (HPM) weapons and ultrawideband (UWB) (or video pulse) weapons. 6, record 1, English, - radio%20frequency%20weapon
Record number: 1, Textual support number: 2 CONT
The primary distinction between RF weapons and more conventional EW systems is that RF weapons actually affect the electronics and not just the electronic environment, thereby causing temporary or permanent electronics failure that persists even after the RF beam has been turned off. RF weapons will mainly target receiver systems with in-band HPM [high-power microwave] radiation or computer systems with ultrawideband impulses. 5, record 1, English, - radio%20frequency%20weapon

An instrument combining a pulsed laser transmitter and optical receiver(usually a telescope) with an electronic signal processing unit used for the detection and ranging of various distant targets in the atmosphere, analogous to the principles of operation of microwave radar. 6, record 4, English, - lidar
Record number: 4, Textual support number: 1 CONT
The lidar technique operates on the same principle as radar; in fact, it is sometimes called laser radar. The principal difference between lidar and radar is the wavelength of the radiation used. Radar uses wavelengths in the radio band whereas lidar uses light, that is usually generated by lasers in modern lidar systems. 7, record 4, English, - lidar
Record number: 4, Textual support number: 2 CONT
There are three basic generic types of lidar: range finders, DIAL, and Doppler lidars. Rande finder lidars are the simplest lidars. They are used to measure the distance from the lidar instrument to a solid or hard target Differential Absorption Lidar (DIAL) is used to measure chemical concentrations (such as ozone, water vapor, pollutants) in the atmosphere. Doppler lidar is used to measure the velocity of a target High-resolution DEMs with vertical accuracy as good as 10 cm can be created with Lidar. Lidar is also better able to map bare earth elevations in forested or vegetated areas than other methods because only a single laser pulse needs to be able to reach between trees and the ground. 8, record 4, English, - lidar

Active motion detectors fill the volume in range of the detector with either ultrasonic, microwave, or sonic energy. The transmitted energy forms a standing wave pattern as it reflects from the objects and walls in the room. Some of this energy is reflected back to the detector receiver, where it is received and processed.

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead]. 2, record 10, English, - laser%20velocimeter
