Planar Frequency Diverse Array Receiver Architecture

In this paper, we extend the beamforming theory for frequency diverse arrays (FDA) to planar array geometries and give spatial pattern snapshots from the transmit and receive aspects. This is a natural extension of linear FDA work. Prior to this paper, FDA has only been discussed as either a linear array on transmit or with a receive processing chain that excludes some transmitted signals. We propose a technique that allows all transmitted signals to be seen and processed by each element on receive in a monostatic configuration.
