Receive Channel Architecture and Transmission System for Digital Array Radar

Abstract

An "opportunistic array" is a new digital antenna concept where phased array elements are placed at available open areas over the entire length of the platform. The elements are self-standing transmit-receive modules that require no hardwire connections other than prime power. All synchronization signals and data are passed wirelessly between the elements and a central signal processor. An opportunistic array that is integrated into the hull or superstructure of the warship is called an "aperstructure". This research investigates a wireless local oscillator distribution in the laboratory, which is a necessary requirement for the coherent operation of the array elements. The research also investigates the digitization and synchronization of multiple receive modules with the local oscillator that will determine the viability of the opportunistic array. The wireless distribution of data and control signals between the digital beamformer and transmit/receive modules requires a low-loss, wideband, simple to implement transmission system that is integrated into the structure of the warship. This research investigates several transmission structures and compare their performances.
