摘要： An electronic device includes a transmission antenna, a reception antenna, a signal processor, a quality determining unit, and a controller. The transmission antenna transmits a transmission wave. The reception antenna receives a reflected wave that is the transmission wave having been reflected. The signal processor calculates, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave, a distance between the electronic device and an object that reflects the transmission wave. The quality determining unit determines a quality of the reception signal. The controller performs control for transmitting the transmission wave in an operation mode corresponding to the distance between the electronic device and the object, based on the quality of the reception signal determined by the quality determining unit.

摘要： A laser device is capable of coaxially outputting visible light and invisible light. The laser device includes a seed source outputting the invisible light, a visible light source outputting the visible light, a first wavelength division multiplexing module and N amplification modules, N is a positive integer. The seed source outputs pulsed laser to the amplification modules. The amplification modules perform power amplification on a signal passing therethrough to obtain a signal with power amplified. The first wavelength division multiplexing module performs wavelength division multiplexing processing on the visible light and the invisible light to ensure that an output end of the laser device is capable of coaxially outputting the visible light and the invisible light.

摘要： Systems, methods, and computer-readable media for performing radar operations based on characteristics of a target. First operational limits defining a limit of a detection operation, imaging operation, or some combination thereof can be identified. The first operational limits can be associated with first operational values of operational parameters. Radar waveform parameters to optimize can be identified. Further, first optimal values for the radar waveform parameters can be identified based on the first operational values associated with the first operational limits. Additionally, a first optimized radar signal can be generated using the first optimal values of the radar waveform parameters. The first optimized radar signal can be optimized for the first operational limits. As follows, the first optimized radar signal can be transmitted towards a target area.

摘要： A radar detector including a radar transmitting device, a radar receiving device, an analog-to-digital converter (ADC), and a digital processing unit, and an interference suppression method using the radar detector are provided. The radar transmitting device transmits a first wireless signal. The radar receiving device receives a second wireless signal to generate an analog reference signal in response to the first wireless signal is subdued from being transmitted, and receives a third wireless signal to generate an analog main signal in response to the first wireless signal is not subdued from being transmitted. The ADC generates a digital reference signal according to the analog reference signal, and generates a digital main signal according to the analog main signal. The digital processing unit adjusts the digital or analog main signal according to the digital reference signal to correspondingly suppress interference components in the digital main signal or in the analog main signal.
