Radar Cross Section Reduction of Wideband Vivaldi Antenna Arrays With Array-Level Scattering Cancellation

Abstract: Wideband phased antenna arrays always contribute large radar cross section (RCS) to low-observed platforms. Low-scattering wideband phased antenna arrays are thus highly demanded. This ...

Design of Linear and Planar Arrays With Low Sidelobe Levels and High Directivity Using Two-Way Array Factor

Abstract: Sidelobes (SLs) in the two-way radiation pattern are of serious concern in a radar array. Several techniques have evolved to mitigate the problem, which include amplitude tapering, genetic ...
