Abstract Historically, most radar sensor array processing has been implemented using dedicated and specialized processing systems. This approach was necessary because the algorithm computation requirements were several orders of magnitude higher than any(More)
As field programmable gate array (FPGA) technology has steadily improved, FPGAs have become viable alternatives to other technology implementations for high-speed classes of digital signal processing (DSP) applications. In particular , radar front-end signal processing, an application formerly dominated by custom very large scale integration (VLSI) chips,(More)
Many radar sensor systems demand high performance front-end signal processing. The high processing throughput is driven by the fast analog-to-digital conversion sampling rate, the large number of sensor channels, and stringent requirements on the filter design leading to a large number of filter taps. The computational demands range from tens to hundreds of(More)
African green monkeys (AGMs) are natural primate hosts of simian immunodeficiency virus (SIV). Interestingly, features of the envelope-specific antibody responses in SIV-infected AGMs are distinct from that of HIV-infected humans and SIV-infected rhesus monkeys, including gp120-focused responses and rapid development of autologous neutralization. Yet, the(More)
