In the ground attack mission, the attack plan needs to be formulated and distributed to the attack aircraft based on the threat source intelligence data obtained in advance with the help of the tactical mission planning system. The passive radar reco

In the phased-array radar (PAR) signals from each antenna are transmitted at the same carrier frequency, which yields narrowly focused only angle dependent beampattern. In contrast, in the frequency-diverse-array (FDA) radar signals from antenna arra

Due to the range dependence and time-varying array factor of Frequency Diverse Array (FDA) radar, it can overcome the miss of range variable in traditional phased-array factor and gain loss of Multiple-Input Multiple-Output (MIMO) radar array. In rec

Abstract Multiple‐input multiple‐output with frequency diverse array (FDA‐MIMO) radar has drawn great attention due to providing the range‐angle beampattern via designing the transmit beamforming matrix. In this work, the authors investigate

Abstract The frequency diverse array (FDA) can provide degrees of freedom in both the range and angle domains by controlling the frequency offset across adjacent elements. Nevertheless, the time‐variant problem affects the analysis and application

Abstract Considering the signal model of the frequency diverse array (FDA), the amplitude and phase characteristics cannot be ignored. The beampattern mainly reflects the amplitude characteristics. Existing investigations show that the angle‐range
