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.

Range and angle measurement in a linear pulsed Frequency Diverse Array radar
, 2017 The range-angle coupling in Frequency Diverse Array (FDA) radar is uniquely solved. The array operates as a linear pulsed FDA in the transmission (TX) mode while it operates as a pulsed phased array (PA) in the receiving (RX) mode. The duration of FDA TX
