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. The radar operates as a pulsed FDA in the transmission (TX) mode, while it operates as a pulsed phase array (PA) in the receiving (RX) mode. The low energy of the TX FDA waveform is compensated by the rapid 2D angular scanning together with the use of the cumulative probability of detection scheme.
