Frequency Diverse Array OFDM System for Joint Communication and Sensing [PDF]
International Symposium on Joint Communications & SensingThe frequency-diverse array (FDA) offers a timevarying beamforming capability without the use of phase shifters. The autoscanning property is achieved by applying a frequency offset between the antennas.

Narrow band space scanning two-dimensional linear frequency diverse array radar
The Journal of Engineering, 2019 Two–dimensional (2D) linear frequency diverse array (FDA) concept is extended to scan a 2D wide angular sector. This is achieved by highly unequal frequency increments in orthogonal 2D directions of the array.

Efficient Beampattern Synthesis for Sparse Frequency Diverse Array via Matrix Pencil Method
Sensors, 2022 Due to the introduction of frequency offsets, the pattern synthesis problem of sparse Frequency diverse array (FDA) becomes more complicated than that of the phased array. A typical way to solve this problem is to use a global optimization algorithm, but

Fibroblast growth factor receptor signaling in hereditary and neoplastic disease: biologic and clinical implications. [PDF]
, 2015 Fibroblast growth factors (FGFs) and their receptors (FGFRs) are transmembrane growth factor receptors with wide tissue distribution. FGF/FGFR signaling is involved in neoplastic behavior and also development, differentiation, growth, and survival.

Nested array with time-delayers for target range and angle estimation [PDF]
, 2015 Since a nested phased array cannot directly estimate the range of targets due to range ambiguity, this paper proposes a nested array with diverse time-delayers for target range and angle estimation.

Beampattern analysis of frequency diverse array radar: a review
EURASIP Journal on Wireless Communications and Networking, 2021 Electronic beam steering is an essential feature of state-of-the-art radar systems. Conventional phased array (PA) radars with fixed carrier frequencies are well-known for electronically steering their beam with high directivity.

Glucocorticoid receptor signalling activates YAP in breast cancer [PDF]
, 2017 The Hippo pathway is an oncosuppressor signalling cascade that plays a major role in the control of cell growth, tissue homoeostasis and organ size. Dysregulation of the Hippo pathway leads to aberrant activation of the transcription co-activator YAP ...
