This paper proposes a receiving nested frequency diverse array (FDA) design scheme. The essence of the proposed technique is to construct a new array structure by systematically nesting two or more uniform linear FDA. Using second-order statistics of the received data, it is capable of providing a significant increasing degrees-of-freedom. The frequency increment across the array results in a scan...
Multipath reflection has great influence on the meter-wave radar low-elevation height-finding. In this paper, a computationally efficient method is presented fully using the information included in the received data covariance matrix. This method is proposed according to the spatial smoothing concept and the propagator operator method. The presented method constructs new forward and backward matrices...
