Directional Modulation (DM) techniques provide wireless communication security against
passive eavesdropping by means of specific physical layer characteristics. The original …

The deceptive jamming technique can threaten a synthetic aperture radar (SAR) imaging
system by repeatedly transmitting copied radar signals back to the radar. A conventional …

Frequency-diverse arrays (FDAs) have attracted great attention since being proposed due to
their inherent range-angle-dependent characteristics. A variety of FDA schemes are …

Secure communication in the physical layer (PHY) using frequency diverse array (FDA)
antennas has become a prominent research topic in recent years due to the unique range …

In this study, a true three‐dimensional dot‐shaped beamforming, in which the transmitted
energy in a spatial region (azimuth, elevation, and range) is focused is performed with the …

The frequency-diverse array (FDA) is a promising technology because of its angle-and
range-dependent beam pattern. The FDA has unique properties, such as beam scanning …

Frequency diversity array (FDA) can generate range and angle dependent “S” beam
patterns, but there is a problem of range and angle coupling, which can be well solved by …

Pulsed frequency diverse arrays (FDAs) have recently garnered significant research
attention in radar and sensing applications due to their range-dependent radiation …

Frequency diverse array (FDA) has received much attention due to its capability of forming
range–angle-dependent beampatterns. However, the standard FDA can only provide S …

Frequency diverse arrays (FDA) can produce a periodic S-shaped pattern due to the added
frequency diversity to the array. The auto-scanning capability in FDAs is obtained by …
