Sidelobe reductions in linear and circular phased array antennas based on hybrid synthesis techniques

open access: yes
The concentration of electromagnetic waves within an angular space is made possible by radiating devices, typically realized in the form of an antenna. Hence, energy emitted or received outside of the intended field of view is manifested in the sidelobes

Remote Vibration Estimation Using Displaced-Phase-Center Antenna SAR for Strong Clutter Environments [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2018
It has been previously demonstrated that it is possible to perform remote vibrometry using synthetic aperture radar (SAR) in conjunction with the discrete fractional Fourier transform (DFrFT).

A Three-Dimensional Displaced Phase Center Antenna Condition for Clutter Cancellation

open access: yes, 2014
In moving radar, e.g. airborne radar, the clutter from land and sea needs to be suppressed in order to detect the target. One approach to total cancellation of the clutter is Displaced Phase Center Antenna (DPCA).

Three-Dimensional DPCA With Rotating Antenna for Clutter Cancellation

open access: yes, 2015
In moving radar, e.g. airborne radar, the clutter from land and sea needs to be suppressed in order to detect the target. One approach to total cancellation of the clutter is Displaced Phase Center Antenna (DPCA).
