Commercial radar technology

This paper discusses three commercial, surface radars: automotive, marine and airport surface detection equipment (ASDE). All three have the same primary function: to avoid collisions, and as a secondary function, provide navigational information as a means to prevent collisions. They all operate at low grazing angles, they struggle with the same challenges of target discrimination in heavy clutter, multiple target resolution in weather, multipath environments, false targets and target tracking. With the advent of inexpensive processing, these three markets are emerging with affordable products requiring minimal operator intervention.
