A digital ASIC implementation of a video filter for synthetic aperture radar
- Sandia National Labs., Albuquerque, NM (United States)

Two GaAs ASICs have been designed and implemented for a synthetic aperture radar which eliminate the dc bias in the sampled video data and increase the signal to noise ratio by summing the data across consecutive bursts. The High Pass Filter and Presummer ASICs process data at a maximum sample rate of 170 MHz and 125 MHz respectively. The chips are fully ECL and TTL compatible. The high pass filter is packaged in GigaBit's standard 132-pin ceramic package, while the presummer is packaged in TriQuint's standard 196-pin ceramic package. The presummer has been successfully tested in a prototype synthetic aperture radar at Sandia National Laboratories. The high pass filter has been successfully tested in a high speed test fixture. These ASICs provide flexibility and low power consumption at data rates previously unattainable with comparable hardware. 1 refs., 4 figs.
