Atmospheric scientists need to observe fluctuations in the ionosphere, both to probe the underlying atmospheric physics, and to remove the effects of these fluctuations from other measurements. We have built an FPGA-based, pipelined array processor that allows us to make these observations, in real-time, using passive radar techniques. Our array processor time-multiplexes 16 multiply-accumulators across 1536 radar ranges, performing a pipelined correlation and integration of the radar signal for each range. A DSP-based postprocessor generates real-time range-Doppler profiles of the ionospheric targets.
