Abstract: The personal computer based integrated radar acquisition (PIRAQ) system integrates a programmable timing generator, a digital Intermediate Frequency (IF) processor, and a digital signal processor on a standardized personal computer "add-on" electronic circuit module that accepts standard IF input and produces standard radar display outputs. The digital intermediate frequency processor includes an IF pre-processor, a programmable digital matched filter, and a wide dynamic range digital baseband converter. Implementing the PIRAQ system in digital components on a single electronic circuit module for use in a personal computer provides and efficient, low-cost, portable, and programmable high-performance radar acquisition system hardware base from which radar signals can be digitally processed.
