What technology does the Speedster consist of?
The Bushnell Speedster contains a K-Band microwave RF (Radio Frequency) transmitter whose signal gets reflected by the target object. The reflected signal will have a "Doppler Shift" proportional to the target speed. This Doppler frequency shift is detected in the receiver, amplified, filtered, and then digitized in an Analog to Digital Converter (ADC), and passed onto the Digital Signal Processing (DSP) chip. Using complex algorithms, the DSP chip filters out false and low level return signals, to identify and display the speed of the desired target. The speed along with various statistics and averages are then displayed on the LCD display.
