Modulation Diversity in Waveform Design

Abstract

The goal of the research has been to develop and demonstrate spatially and temporally adaptive radio frequency (RF) sensor technology for application to air, space and ground systems operating in isolation or in concert with other sensor systems. The objective has been to be aware of the environment as it is critical to the process of spatial and temporal diversity via both transmit and receive. The idea here is to use the environment as part of the RF sensor system, thereby improving the transmission and reception efficiency. Improved target (air to ground) detection will be achieved under this effort. So not only polarization but also integration of the surrounding environment including the platform is used to optimize the performance for different radar configurations and geometries. Another aspect of the research had been on the design of waveforms for efficient spatial-temporal adaptively including the focusing of the transmitted energy on the target.
