Background & Objective: In this paper contactless human fall detection system has
been designed, developed and tested.
Methods: Continuous wave radar system is implemented at 2.10 GHz of frequency. It consists of
transmitter and receiver section. In Radio Frequency (RF) transmitter system is developed with the
use of frequency synthesizer, power amplifier and patch antenna for the transmission of 2.10 GHz.
Similarly, at the receiver side 2.1001GHz of frequency signal is generated with the use of frequency
synthesizer. For the measurement of the fall detection high frequency signal is down converted to
100 KHz of signal with the use of mixer. Number of experiment has been performed for the measurement
of fall detection. Here non-living object has been used for the experimental purpose.
Results & Conclusion: A fall event has been detected according to the change in the received frequency
in respect with the reference frequency.
