| Summary: | The increasing number of motor vehicles in Indonesia has led to a significant rise
in traffic accidents. One contributing factor is the lack of advanced safety systems
in many vehicles, particularly entry-level models. To address this issue, this
research focuses on developing an affordable and easily integrable Radio
Frequency (RF)-based forward sensing system for entry-level vehicles. The system
utilizes FMCW (Frequency Modulated Continuous Wave) radar technology
operating at 6 GHz. This frequency was chosen due to component availability,
adequate spectrum allocation in Indonesia, and its ability to provide good detection
resolution with minimal interference from the surrounding environment. The main
components of the system are a microstrip patch antenna and a transceiver. The
microstrip patch antenna was selected for its simple structure, low fabrication cost,
low profile, and ease of integration with vehicles. The antenna design was
optimized to operate at 6 GHz using CST software. Various antenna configurations,
including 1-array, 2-array, and 4-array, were simulated and analyzed to achieve
the best performance in terms of return loss, VSWR (Voltage Standing Wave Ratio),
and gain. Test results showed good agreement between simulation and
measurement results, validating the antenna design. In addition to the antenna, a
transceiver was also designed and built using SDR software, based on an FMCW
block diagram. The SDR was designed to operate at the desired frequency of 6 GHz
and has a bandwidth of 50 MHz, allowing it to work well with a range resolution
of 3 meters. The integrated system, consisting of the antenna and SDR transceiver
circuit, has been tested through a series of indoor and outdoor tests, meeting the
objectives required for developing an automotive radar suitable for assisted driving
applications |
