Digital wideband receivers are essential elements used in electronic warfare (EW) applications. Instantaneous Frequency Measurement (IFM) receivers are suitable for use in EW systems due to the ultrawide instantaneous radio-frequency (RF) bandwidth, fine-frequency resolution, and moderately high sensitivity and dynamic range. Conventional IFM receivers use analog components such as power dividers, crystal video detectors, and hybrids. This research presents the architecture and design implementation of a purely digital IFM receiver based on a patented algorithm courtesy of the United States Air Force. The invention is capable of detecting a short wave pulse with 1 MHz error for every 100 nsec. The benefits include a compact, lightweight, cost-effective alternative to its analog counterpart. The design was implemented and tested on Delphi's ADC3255 (a PMC digitizer with Xilinx Virtex 4 FPGA). The outputs were verified using Xilinx's ChipScope Pro.
