A target detection and imaging system, comprising a RADAR unit and at least one ultra-low phase noise frequency synthesizer, is provided. The target detecting, and imaging system can assist other sensors such as LiDAR, camera to further detect and investigate objects on the road from distance. RADAR unit configured for detecting the presence and characteristics of one or more objects in various directions. The RADAR unit may include a transmitter for transmitting at least one radio signal; and a receiver for receiving the at least one radio signal returned from the one or more objects. signals. The ultra-low phase noise frequency synthesizer may utilize dual loop design comprising one main PLL and one sampling PLL, where the main PLL might include a DDS or Fractional-N PLL plus a variable divider, or the synthesizer may utilize a sampling PLL only, to reduce phase noise from the returned radio signal. This proposed system overcomes deficiencies of current generation state of the art RADAR Systems by providing much lower level of phase noise which would result in improved performance of the RADAR system in terms of target detection, characterization etc.

RADAR target detection system for autonomous vehicles with ultra lowphase noise frequency synthesizer

A system for providing ultra low phase noise frequency synthesizers using Fractional-N PLL (Phase Lock Loop), Sampling Reference PLL and DDS (Direct Digital Synthesizer). Modern day advanced communication systems comprise frequency synthesizers that provide a frequency output signal to other parts of the transmitter and receiver so as to enable the system to operate at the set frequency band. The performance of the frequency synthesizer determines the performance of the communication link. Current days advanced communication systems comprises single loop Frequency synthesizers which are not completely able to provide lower phase deviations for errors (For 256 QAM the practical phase deviation for no errors is 0.4-0.5&#xb0;) which would enable users to receive high data rate. This proposed system overcomes deficiencies of current generation state of the art communication systems by providing much lower level of phase deviation error which would result in much higher modulation schemes and high data rate.
