| Summary: | A Frequency Modulated Continuous Wave
(FMCW) Doppler radar was assembled to detect human as
sample target. Its operating frequency is at 2.4GHz with
transmitting power of 10.41 dBm. Range resolution of the radar
is 2.8 meters at 53.2MHz signal bandwidth and chirp waveform
of 40ms. The radar exploits Doppler principle to acquire the
range and velocity information of targets whilst a Moving
Target Indicator (MTI) pulse canceller is utilized to filter
incoming noise signal. With the use of Chirp period-bandwidth
product Frequency Modulated (FM) waveform and deramping
process, the radars’ Signal to Noise Ratio (SNR) was improved
up to 42 dB. The attained maximum range is about 200 meters
for a target with Radar Cross Section (RCS) of 1m2
. The
constructed radar is capable to measure the speed of moving
target at 0.645m/s and above with great accuracy. The radar can
detect and determine the position of pedestrians with 0.18%
percentage error. |
