Abstract: An object detection method and apparatus is disclosed, where the object detection method includes determining a weather condition based on a noise floor measured in an elevated direction, and detecting an object based on comparing a signal level of a target signal measured in a depressed direction and a threshold level corresponding to the determined weather condition.

Abstract: A method performed by an apparatus included in a vehicle to detect an object using a radar includes: propagating, in a normal mode period of an operating period for detecting objects, a normal mode transmission signal generated based on a default code sequence including at least two codes; receiving a normal mode reception signal in the normal mode period; detecting, in the normal mode period, an object based on the default code sequence and the normal mode reception signal; receiving a listening mode reception signal in a listening mode period of the operating period; acquiring a correlation between the listening mode reception signal and the default code sequence; and changing the default code sequence based on the correlation.

Abstract: A phase locked loop includes a signal receiver configured to generate a mixed signal based on the received signal and an oscillator signal, and a frequency control circuit configured to compare the mixed signal to a reference signal, and adjust the oscillator signal based on a result of the comparing.

Abstract: A transceiver may include a reception (Rx) radio frequency (RF) part configured to process a received signal, a transmission (Tx) RF part configured to process a transmitted signal, and a phase lock loop (PLL) configured to provide a reception frequency to the reception RF part and provide a transmission frequency to the transmission RF part. The PLL may be controlled according to whether the reception RF part or the transmission RF part is on. In addition, a transceiver may include quenching waveform generator (QWGs) to control quenching waveforms of the RF parts corresponding to a plurality of antennas. The quenching waveforms may be generated respectively by VCOs operating at a same frequency. The QWGs may control the VCOs such that the quenching waveforms do not overlap.
