Abstract
This dissertation considers the optimization of radar performance within the structure imposed by a coded
Orthogonal Frequency Division Multiplexing
(OFDM) format required to achieve an acceptable communication link. The dual goal of achieving both satisfactory radar and communication performance raises challenges that can be substantively addressed by combining phase coding and modulation techniques to provide the temporal and spectral structure necessary to implement simultaneous radar and communication operations. In particular, the specific techniques, as introduced within this dissertation, of using the
Multi-Frequency Complementary Phase Coded
(MCPC) sequences, as prescribed by Levanon and Mozeson, for simultaneous radar and wireless communication operations represent a novel contribution and offers a significant improvement in the study, implementation, and performance of dual use radar and communication waveforms and signal processing techniques. Specific contributions of this dissertation include: 1) as will be demonstrated, not all valid MCPC sequences can be used for data transmission, and, therefore, a subset of MCPC sequences are chosen with consideration to radar detection performance, 2) communication operation is improved through the introduction of an algorithm that enables Gray codes to be applied to MCPC sequences, 3) the orthogonality of MCPC sequences is exploited to overcome the effects of multipath fading and intercarrier interference, 4) a new detector type, termed the Beta detector, is developed for both communications operations and radar detection, 5) a radar detection method, termed
Polar Signal Detection
, is developed that combines the Beta detector with a traditional matched filter detector to achieve superior detection performance as compared to traditional
Cell-Averaging Constant False Alarm Rate
(CA-CFAR) detectors in multi-target environments, and 6) a novel method of measuring Doppler frequencies is introduced that is superior to the measurement performance of traditional radar systems.
