Spectrum Monitoring

Military SpectrumSpectrum monitoring can effectively help enforce compliance with international radio traffic regulations, as breaches can be recognized in time by means of radio surveillance and radio monitoring.


Radio traffic is governed by international regulations.  This is to ensure that when police, radio stations, air traffic control and radio hams are all on the air at the same time, they do not cause mutual interference.  Compliance with regulations is enforced by radiomonitoring, which is also an advantage in combating organized crime.


Any factors jeopardizing national security can be recognized in time by means of radio surveillance, which is thus an important and effective means of maintaining peace.

dB or not dB?

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This application note is intended as a refresher on the subject of decibels. View application note here

Coexistence Test of LTE and Radar Systems - 1MA211

Air Traffic Control (ATC) radar, military Air Traffic Surveillance (ATS) radar and meteorological radar operate in S-Band frequency range. In fact 4G communication systems such as Long Term Evolution (LTE) make also use of these frequencies. Test and measurement of their coexistence is absolutely essential as performance degradation of mobile devices and networks and even malfunction of ATC radars has been proven. This application note describes LTE and S-Band radar coexistence test and measurement. It addresses LTE user equipment, base stations and S-Band radars and presents test solutions. View application note here
