The ICs will be implemented using a few advanced silicon-based and III-V compound semiconductor technologies to achieve the design goals of high resolution, small size, low weight and low dc power consumption. The center frequency is 77 or 94 GHz with a bandwidth of 2 GHz. The radar has the capability of range and speed detection. The RF output signal of the transmitter is modulated using a pulse to enhance sensitivity and lower dc power consumption. The peak RF output power is 10 dBm with a detection range of 10 m. The average dc power consumption of the frontend ICs is lower than 0.2 W. The research works contain the development of the system analysis, millimeter-wave (MMW) ICs, and the package technology for the MMW radar. The developed ICs consists of power amplifiers, low noise amplifiers, modulator, down converter, and the local oscillation source. The developed frontend ICs and modules will be employed in the UAV for assisted autopilot, collision avoidance and sensing. For the transmitting chain, we will focus on the research of power combing to further enhance output power and DC-to-RF efficiency. For the receiving chain, we will focus on the research of noise figure reduction and conversion gain enhancement. In addition, an innovative sub-harmonically injection-locked frequency-locked loop will be employed to lower phase noise. We will achieve the establishment of the MMW radar technology, the innovative ICs, the related measurement technology, and the innovative frontend ICs and modules. The system planning, IC design, chip layout, fabrication and chip evaluation will be exercised. The design will also be completed and sent to the foundry for fabrication. In last, the measurement and analysis of the developed MMW frontend ICs and modules will be carried out.
