An Overview of Frequency Diverse Array Radar Technology
Leida xuebao, 2018 The carrier frequencies of array elements in a Frequency Diverse Array (FDA) radar are slightly distinguished, leading to a range-angle-time-dependent transmit beampattern. Thus, an FDA radar carries additional information in a certain range and provides

Cognitive FDA‐MIMO radar for LPI transmit beamforming
IET Radar, Sonar & Navigation, 2017 Active radar is vulnerable to illegal eavesdroppers due to its high‐gain beam‐scanning signals. To reduce active radar visibility and enhance its low probability of intercept (LPI) capability, this study proposes a cognitive LPI transmit beamforming scheme using frequency diverse array (FDA) and multiple‐input multiple‐output (MIMO) hybrid array ...

Fast algorithm for moving target localisation using FDA‐MIMO radar [PDF]
The Journal of Engineering, 2019 Target localisation using frequency diverse array (FDA) has drawn much attention owing to the additional degree of freedom in the range dimension. However, the Doppler effect was often ignored in previous FDA works because of the stationary target assumption, and in contrast, even stationary target localisation could be of quite a high computational ...
