Wide-spatial radar surveillance missions are challenging tasks,requiring an increased power budget and agility in transmission aimed at extracting information from multiple targets in different en-vironments.These requirements necessitate high transmitting degrees of freedom(DOF)to achieve the objective of multiscale observation for specific tasks in specialized regions of interest.Herein,we exploit the multiscale observation ability in wide-spatial radar surveillance based on frequency diverse array(FDA)radar.The proposed method facilitates spatial anisotropic control of multiple radar resources,including the transmitting waveforms,beampattern,and bandwidth.By utilizing a coherent FDA radar,we offer principles for the selection of baseband waveforms,in addition to the quantitative design of the beampattern gain and optimal bandwidth from the perspective of detection.The feasibility of the proposed method is validated through numerical experiments,thus indicating the potential in wide-spatial radar surveillance.Moreover,this work can be regarded as a preliminary attempt to gauge the efficacy of the computational array,a novel academic concept.
