Wide-Scanning Conformal Phased Array Antenna for UAV Radar Based on Polyimide Film

IEEE Antennas and Wireless Propagation Letters, 2020
Polyimide film is a practicable alternative to the conventional substrates utilized in conformal antennas. Due to its flexibility, the antennas based on the polyimide film can be easily conformed to the platform surface.

Phased arrays in radar

Electronics & Communication Engineering Journal, 1990
Array antennas were used in early radar systems. Today's microwave phased arrays with electronic beam-steering allow surveillance and tracking with variable data rates in a multifunction radar. The paper reviews system options and discusses the engineering of active arrays, using as an example the Siemens Plessey Radar/ARE MESAR, which is now ...

The Jicamarca phased-array radar

2013 IEEE International Symposium on Phased Array Systems and Technology, 2013
Phased array and spaced antenna radar techniques developed and employed at the Jicamarca Radio Observatory for ionospheric research are reviewed. The ionospheric scatterers studied by Jicamarca are not spatially homogeneous and not beam filling in some cases, and distinguishing the bearing of the radar backscatter is essential for correctly ...
