- Abstract
- The real-time radar system is implemented using a prototype CMOS impulse radar and a DSP (Digital Signal Processor) chip for human detection. Human motions such as walk, breathing are successfully measured. The received signals of the prototype radar at high resolution (1.5 cm) with sufficient SNR are utilized. A commercial DSP chip is used to process received data. The radar signal processing for detecting a walking man and human respiration is proposed. The pulse integration as a part of radar signal processing is used for SNR improvement, also MTI (Moving Target Indicator) processing including maximum detector, comparator and direct coupling rejection is used for increasing detection probability about human target. The experiments on a walking man and human respiration are performed, and measurement results are discussed. © 2013 IEEE.
