| Summary: | 碩士 === 國立交通大學 === 電機學院電信學程 === 101 === In this thesis presents a multi-target detection algorithm for 24GHz vehicle collision warning radar (1T2R architecture). In order to achieve the lower sampling frequency and the lower computation time.We take use of multi slope radar waveform for multi-target detection algorithm. It archive to detection multiple target simultaneously for 24GHz vehicle collision warning radar (1T2R architecture).according to our proposed algorithm we could simultaneously determine the multi target's angle, distance and speed with the 1T2R antenna architecture. The requirements of the hardware specification of the proposed algorithm is lower than the 2D FFT algorithm, by the DSP processing performance calculation, the MCU (ARM-M3 MCU) architecture could achieve the digital signal processing parts of vehicle collision warning radar. Using the MCU chipset to achieve the expensive DSP chip, it cost down the hardware cost of the vehicle collision warning radar.
Finally, by the simulation results will be illustrated to verify the feasibility of the algorithm. Many situations are taken into consideration to ensure the simulation environment close to the real case. At the same time, targets’ distance, speed, angle information and targets’ characteristics will be combined together for further tracking and detection.
