Frequency diverse array with random logarithmically increasing frequency offset
, 2020 The frequency diverse arrays (FDAs) have been extensively investigated since it can provide a unique angle‐range‐dependent beampattern. This range‐dependent characteristic can suppress the range ambiguous clutters, leading to many novel potential Radar ...

Joint Decoupling Optimization of Frequency Offsets and Array Elements for Frequency Diverse Arrays
International Journal of Antennas and PropagationFrequency diverse array (FDA) has a distance-angle–dependent beam direction map, which has a greater application advantage than phased array. However, due to the distance-angle coupling and periodicity of its beam direction map, it makes the parameter ...

Narrow band wide angle scanning circular frequency diverse array radar
, 2017 One dimensional Linear Frequency Diverse Array (FDA) is extended to a circular two dimensional FDA array (CFDA). The CFDA operates as a pulsed FDA in the transmission (TX) mode while it operates as a pulsed phased array (PA) in the receiving (RX) mode ...

Beampattern Synthesis for Frequency Diverse Array Based on Time-Modulated Double Parameters Approach
The basic frequency diverse array (FDA) using linearly increasing frequency increments generates a range-angle dependent beampattern. However, it is coupled in range and angle dimensions and is also periodic in range and time, making its applications ...
