Waveform Diversity and Range-Coupled Adaptive Radar Signal Processing
Waveform diversity may offer several benefits to radar systems though often at the cost of reduced sensitivity. Multi-dimensional processing schemes are known to offer many degrees of freedom, which can be exploited to suppress the ambiguity inherent to pulse compression, array processing, and …

Transmit Signal Design for MIMO Radar and Massive MIMO Channel Estimation
… for a MIMO radar transmit scheme which trades o waveform diversity for beampattern directivity. Time-division beamforming consists of a linear precoder that provides direct control of the transmit beampattern and is able to form multiple transmit beams in a single pulse. The MIMO receive …

Radar intra-pulse modulation classification using convolutional neural networks
… schemes. Recent years have seen increased waveform diversity in radar systems which, while making many aspects of pulse analysis more challenging, have presented new opportunities and features for the _eld of classification. This dissertation aims to address the increasing difficulty of …

Adaptive MIMO Radar for Target Detection, Estimation, and Tracking
… Distributed MIMO radar exploits spatial diversity by utilizing multiple uncorrelated looks at the target. Colocated MIMO radar systems offer performance improvement by exploiting waveform diversity. Each antenna has the freedom to transmit a waveform that is different from the waveforms …

Adaptive Radar with Application to Joint Communication and Synthetic Aperture Radar (CoSAR)
… non-traditional, specifically, communication waveforms for remote sensing. A software defined radar (SDR) is developed. The SDR features a "closed loop" testbed interface accessible via Matlab m-code. Here, "closed-loop" means that data can be pulled from the SDR, processed, then used to …

Practical Considerations for Radar Embedded Communication
… examining some of the practical aspects of the waveform design. Communication waveform mismatches between the tag and receiver due to multipath distortion, sampling rate differences and using different lengths for the radar waveform are explored for each of the three previously developed design …
