  • Publication number: 20240125911
    Abstract: The present disclosure relates to a pulse radar device comprising a memory that includes a first memory and a second memory, each storing a scan vector. The device also includes a clock generator that produces a transmission clock signal and a reception clock signal. The reception clock signal is generated by delaying the transmission clock signal by a clock delay value. Furthermore, the device includes a transmitter that generates a transmission pulse by accepting the transmission clock signal from the clock generator and emits the pulse. Additionally, the device includes a receiver that receives an echo pulse reflected from a target by accepting the reception clock signal from the clock generator. The receiver then calculates the received echo pulse to generate a representative scan vector.
