CMBEI-C (Combined Microwave and Balanced Electronic Interference Generators) are interference generators used to generate broadband noise pulses and injection of precise single frequency noise sources in electrically balanced systems. This device is used in many different application fields such as generating controlled multipath environments, interference cancellation systems, radar systems and satellite communication systems. In this article, we will discuss about the application field of CMBEI-C along with its working principle.

The main application field of CMBEI-C is to generate controlled multipath environments, or in other words, it is used to simulate multipath interference. Multipath interference is a situation in which, due to the reflection of the signal from nearby obstacles, multiple copies of the same signal reach the receiver at different times. This type of interference was usually simulated in the laboratory by using a large number of receivers and transmitters or by using a mathematical model to generate the multipath signals. However, CMBEI-C make this process much easier and efficient, as it only requires a single device for the generation of interference. CMBEI-C are also used in interference cancellation systems for the removal of noise from a particular receiving antenna.

CMBEI-C are also used in radar systems. Radar systems are used for the detection and location of objects in the environment. In order to accurately detect the object, the radar system needs to receive a highly precise signal which is free from all types of noise. The CMBEI-C are used in order to reduce the effect of multipath interference which can degrade the performance of the radar system. Furthermore, CMBEI-C can also be used for simulation of radar sensors for testing and development of new radar systems.

Lastly, CMBEI-C are used in satellite communication systems as well. In satellite communication, the signal must travel long distances in space before reaching the receiver. Since this signal passes through the atmosphere, it is more susceptible to interference. CMBEI-C can be used to simulate the multipath interference that can affect the communication and to study new techniques for interference mitigation. Furthermore, CMBEI-C can also be used to generate controlled noise sources which can be used to study the effect of noise on satellite communication systems.

Now let us discuss the working principle of CMBEI-C. CMBEI-C utilize a combination of electronic and microwave techniques for generating broadband noise pulses or single frequency noise sources. It uses an injection-locked technique for generating the broadband noise pulses. This technique involves the injection of an interfering signal into an oscillator, which is locked to the signal. This causes the oscillator to produce a pulse of noise with the same frequency as the injected signal. This noise pulse is then fed to the receiver, which generates the desired broadband noise pulse.

The device also utilizes an electronic balancing technique for the generation of single frequency noise sources. In this technique, two signals of opposite phase and frequency are generated and then combined to form a single signal with reduced amplitude. This signal is then fed to the receiver, which generates the required single frequency noise source.

To summarize, CMBEI-C are interference generators used to generate noise pulses and injection of precise single frequency noise sources in electrically balanced systems. They are mainly used in the application fields of generating controlled multipath environments, interference cancellation systems, radar systems and satellite communication systems. The working principle of CMBEI-C is based on the injection-locked technique for broadband noise pulses and balancing technique for single frequency noise sources.
