  • Adaptive null-steered interference-rejection for a mobile satellite receiver

    Phased Array Systems and Technology (ARRAY), 2010 IEEE International Symposium

    One of the most useful applications of antenna arrays is interference rejection. This paper describes an antenna array that was designed for the sole purpose of rejecting interference of a satellite receiver from a close-proximity jamming source. Since this jammer can move relative the satellite antenna, the antenna array must adaptively adjust its null direction accordingly. The system consists of a six-element array of circular fractal patch antennas in conjunction with a receiver channel…

  • Broadband-Interference Rejection for Mobile Satellite Receiver

    IEEE International Conference on Wireless Information Technology

    Electromagnetic interference can disrupt mobile satellite communications in both military and commercial mobile applications. Not only is this true when a high-power terrestrial source is in close proximity to a mobile satellite receiver, but it can be especially problematic when the vehicle or nearby vehicle has its own onboard interference source that overpowers the desired satellite signal. This can cause interference even if that interfering signal were out of the frequency band of the…

    Electromagnetic interference can disrupt mobile satellite communications in both military and commercial mobile applications. Not only is this true when a high-power terrestrial source is in close proximity to a mobile satellite receiver, but it can be especially problematic when the vehicle or nearby vehicle has its own onboard interference source that overpowers the desired satellite signal. This can cause interference even if that interfering signal were out of the frequency band of the desired satellite signal, due to non-ideal filtering. To exacerbate this problem, many of these sources are ultra wideband (UWB), consisting of electromagnetic energy spread over a very large bandwidth that may overlap the desired satellite channel. In this case even the fraction of the UWB interfering power that is in-band, could potentially overpower the satellite signal power. Algorithms exist that suppress interference in narrow and broadband applications. So, rather than introduce another exotic algorithm, this paper discusses a relatively simple system for broadband interference rejection that takes advantage of the difference in bandwidths between broadband interference and a narrowband satellite signal. This is achieved by adding an interference-detection channel to the satellite receiver that adaptively steers an antenna-pattern null, in order to reject terrestrial interference caused by emitters from nearby military vehicles, as well as onboard the receiver's own vehicle.

Projects

  • Anti-Jamming Antenna Array

    We needed to find a new solution to allow satellite communications in the presence of jammers that were being used to prevent remote detonation of improvised explosive devices. I led a six person team in the design, build and test of a prototype anti-jamming antenna array. Along with leading the team, I was personally responsible the array and antenna design of the project. The final design was a six element circular array with probe fed circular patch antennas capable of electronically…

    We needed to find a new solution to allow satellite communications in the presence of jammers that were being used to prevent remote detonation of improvised explosive devices. I led a six person team in the design, build and test of a prototype anti-jamming antenna array. Along with leading the team, I was personally responsible the array and antenna design of the project. The final design was a six element circular array with probe fed circular patch antennas capable of electronically steering a null in any direction to suppress intentional or unintentional jamming interference. New methods that we developed led to two peer reviewed publications.

  • RF-Distinctive Native Attribute (RF-DNA) Fingerprinting

    -

    Using statistical analysis of emitted signals from a given device used in a communication network, the device can be classified down to make, model and serial number.​
