SN8VPPB (Spherical Near-Field Scanner Particle Beam) is a new type of antenna array that has been developed through the collaboration of experts from antenna array design and radio frequency engineering. This antenna array is particularly suitable for wide-band measurements, like direction of arrival (DOA) estimation, location of sources, channel sounding, and antenna radiation pattern determination. It offers a significant improvement in terms of speed and accuracy when compared to traditional antenna array methods.

SN8VPPB technology is based on an array of point sources, where their electromagnetic fields are interacting and producing beamforming patterns of radiated energy. The point sources in the array are either isotropic or collinear in nature and they are modulated with a relatively low-power signal that provides a specific distribution in the radiation field necessary for the desired radiation characteristics. The output of the SN8VPPB array is then amplified and combined to create the desired beamforming pattern from the source.

In terms of applications, this type of antenna array can be used for a wide range of purposes. In the radio astronomy field, for example, the SN8VPPB array can be used to measure radio sources in the sky and help scientists to identify and map its structure. For radar applications, the SN8VPPB array can be used to track objects and determine their motion. It can also be used to measure antenna radiation patterns and determine the best management and deployment of antennas. These use cases represent just some of the potential applications of this technology.

In terms of working principle, SN8VPPB implements an array of antennas formed by a number of point sources. Each point source has limited radiation characteristics and, by combining them in a certain way, the beamforming pattern of the antenna array is obtained. This is done by modulating the signals of the point sources, amplifying, combining and controlling the desired radiation pattern. The construction of the SN8VPPB array and the specifics of its operation can vary from one application to another and need to be designed depending on the particular requirements.

To sum up, SN8VPPB is a new type of flexible antenna array technology that can be used for a variety of applications, such as DOA estimation, location of sources, channel sounding, and antenna radiation pattern determination. By combining point sources in a special pattern, it is possible to obtain the desired output beamforming pattern, depending on the specifics of each application. The success of this technology relies on the proper design of the array and its operation, making sure to obtain the optimal results for each particular application.
