    Abstract: A signal converting apparatus includes a comparing device, a first digital-slope quantizer, and a second digital-slope quantizer. The comparing device has a first input terminal and a second input terminal for receiving a received signal and an adjustable reference voltage respectively, and for generating an output signal at an output port. The first digital-slope quantizer is coupled to the output port and the second input terminal for generating a first set of digital signals to monotonically adjust the adjustable reference voltage at the second input terminal during a first phase according to a first quantization unit. The second digital-slope quantizer is coupled to the output port and the second input terminal for generating a second set of digital signals to monotonically adjust the adjustable reference voltage at the second input terminal during a second phase after the first phase according to a second quantization unit.

    Abstract: The present application discloses a radar system. The radar system includes a first subarray, a second subarray, and a third subarray. Antennas in the first subarray and the second subarray are disposed along a first axis, and antennas in the third subarray are disposed along a second axis. When scanning a radar coverage of the radar system, the radar system utilizes the first subarray and the second subarray as RF signal transceivers and utilizes the third subarray as a RF signal receiver to scan a first detection distance range according to first signal parameters and scan a second detection distance range according to second signal parameters. A maximum distance measured from the radar system to each detectable location in the first detection distance range is less than or equal to a minimum distance measured from the radar system to each detectable location in the second detection distance range.
