Nonlinear Frequency Offset Beam Design for FDA-MIMO Radar. [PDF]
Sensors (Basel), 2023 The beam pattern of frequency diversity array (FDA) radar has a range–angle two-dimensional degree of freedom, which makes it possible to distinguish different targets from the same angle and brings a new approach to anti-jamming of radars. However, the beam pattern of conventional linearly frequency-biased FDA radar is range–angle-coupled and time ...
