Abstract In this paper, we have proposed a double pulse multiple input multiple output–
frequency diverse array (MIMO–FDA) radar to improve the range-angle localization of the
target. Although frequency diverse array (FDA) radar has been widely used to generate both
range and angle dependent beamforming, however, it is difficult for FDA to localize the target
in both dimensions due to strong coupling of range and angle dimension. To overcome this
inability of FDA radar, a double pulse based MIMO–FDA has been presented here. MIMO–
FDA can be obtained by partitioning of FDA transmit array into subarrays and then transmit
a unique waveform from each subarray. The resultant MIMO–FDA radar will send a pulse
with zero frequency increment to locate the target in angle dimension, which is followed by
a pulse with suitable frequency increment to locate the target in range dimension. Using the
MIMO–FDA radar with double pulse method has improved the range-angle localization of
the target. Simulations and results have verified the effectiveness of the proposed radar. The
Cramer Rao lower bound for the proposed radar has also been derived and compared with
the double pulse FDA radar.
