Abstract

© 2020 Turkish Chambers of Electrical Engineers.In this study, a low-cost pulse radar system has been developed using X-band microwave motion sensor module HB100, low noise block (LNB) and analog satellite finder to ensure environmental safety. A square wave from a function generator is generated in order to modulate the 10.525 GHz carrier signal generated by HB100 module, this modulated signal can detect a fixed target range with a separate receiver system. The reflected weak signal from the target is amplified and down-converted to a low frequency by the help of LNB used at the receiver side. Another part of the receiver is the analog satellite finder, that is used as a power detector which demodulates the signal received from the LNB then the demodulated signal is observed at the oscilloscope. A low-cost radar system that can detect targets up to 168 meters has been built where the HB100 module is used as a high frequency carrier signal generator at the transmitter part of the system the LNB and analog satellite finder are used at the receiver part of the system.
