5 New Things to Do with a Single-Chip Radar
In case you didn’t know, you are living in the age of the single-chip radar. These chips are now widely used in automobiles, so volume is increasing—thereby reducing the price. This makes them ever more practical for other applications, which got me to thinking: What are these other apps? Here are a few thoughts.
The single-chip radars come in a variety of forms. You can get them in the 24, 60, 76-77, and 94 GHz bands. Some research-lab chips operate at 120 GHz. As for modulation, there are CW and pulse types—but most seem to use FM-CW. There are even some impulse UWB units available. Maximum range is about 10 to 60 meters. Most are made with SiGe, but there are some CMOS devices emerging. Prices are still in the high single digits, but coming down. A number of companies offer complete modules, especially for auto use.
