SOUND RADIO LIGHT HARMFUL RADIATION VHF = VERY HIGH FREQUENCY UHF = ULTRA HIGH FREQUENCY SHF = SUPER HIGH FREQUENCY EHF = EXTREMELY HIGH FREQUENCY 4G CELLULAR GHz GHz ISM band ISM bands MHz UWB GHz ISM = Industrial, Scientific and Medical UWB = Ultra Wide Band. is a frequency hopping system used to protect military UHF radio the end of World War II, U.S. and Allied military aircraft have used AM radios in the ndash; MHz UHF band for short range air to air and ground to air.

Concepts and Characteristics. Frequency hopping is the periodic changing of the carrier frequency of a transmitted signal. The sequence of carrier frequencies is called the frequency-hopping pattern. The set of M possible carrier frequencies { f 1, f 2,, f M} is called the hopset. The rate at which the carrier frequency changes is called the hop rate. The process of frequency hopping requires four data elements or variables. They are: (1) a hopset, which is a group of frequencies (30 to MHz) that the radio uses; (2) a TRANSEC (TSK) key, which is used in selecting the frequency hopping sequence; (3) a NET ID, a three digit number from to that fixes the hopping start point; and.

Thus, it will be subjected to hostile EW efforts, e.g., jamming, direction finding, interception, etc. therefore, the aim of this thesis is to carry out a comparative evaluation of several state-of-the-art frequency hopping combat net radios in order to select the best available choice.

single channel ground and airborne radio system (sincgars) synopsis: sincgars provides vhf-fm ( megahertz) combat net radio communication with eccm capability (frequency hopping) and digital.

Single Channel Ground and Airborne Radio System (SINCGARS) is a Combat Net Radio (CNR) currently used by U.S. and allied military forces. The CNR network is designed around three systems: SINCGARS, the high frequency (HF) radio, and the SC tactical satellite (TACSAT).

Each system has different capabilities and transmission characteristics. Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same.

FASTNET is the latest tactical VHF radio from THALES. It offers multiple waveforms in frequency hopping, including a new (time multiplex based) waveform called GEOMUX.

Multipath situations had been identified and synchronization multipath related changes had been designed for the previous radio generation for Switzerland. HF Frequency Hopping Radio. From the Vietnam War to contemporary applications It is against this backdrop that the requirement for a secure combat net radio emerged - ie.

one that could not be intercepted or jammed. In the late s the US put forth a tender document for a system known as SINCGARS (SINgle Channel Ground and Airborne Radio.

Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many distinct frequencies occupying a large spectral changes are controlled by a code known to both transmitter and is used to avoid interference, to prevent eavesdropping, and to enable code-division multiple access (CDMA).

The Net I D is one factor in determining the point at which the SINCGARS radio will start hopping within the frequency hopset.

(4) C S (Call Sign) - This data field identifies a sign (code), in letter/number/letter format, that is used to identify a specific radio net name within a time period of a SOI. This manual serves as a reference document for combat net radio (CNR) systems.

It does not replace field manuals governing combat, combat support (CS), or combat service support (CSS) unit tactical deployment or technical manuals on equipment use. This manual provides guidance for using single-channel radios on the modern battlefield.

The Defence Acquisition Council (DAC) has approved a deal with an Israeli firm to buy 4, combat net radio (CNR) sets, defence ministry sources told this newspaper. Of course, several other inventors had their own takes on frequency hopping and eventually the U.S.

government got with the program. Inthe. The technology Hedy Lamarr helped invent is frequency-hopping spread-spectrum (FHSS) radio technology. FHSS is a wireless technology that spreads signals over rapidly changing frequencies.

Each available frequency band is divided into subfrequencies. Signals rapidly change, or “hop,” among these subfrequency bands in a pre-determined order. Frequency Hopping is a technique based on principals of spreading a signal among a wide range of frequencies to prevent interference and signal detection by hopping the carrier frequency.
