The invention discloses an X wave band radar based navigation and wave detection integrated system. The system includes a display console, an antenna and a servo transceiver unit which are connected in order. The display console includes a host unit, a display unit, a control unit, and a ship power supply. The host unit is connected to the display unit and the control unit. The host unit includesa radar mainboard, a radar control board, a signal processing board, and a power supply module. The radar mainboard is connected to the radar control board, the signal processing board, the display unit, the control unit, the ship power supply, and the servo transceiver unit. The servo transceiver unit includes a servo unit and a transceiver unit. The servo unit includes a motor transmission device and an azimuth and ship bow pulse forming circuit which are connected in order. The transceiver unit includes a performance monitor, a transmitter and a receiver which are connected in order. The system integrates navigation and wave detection functions, is suitable for a shipborne mobile and offshore platform and shore-based fixed applications, and meets the requirements of maneuver detection and nearshore detection.
