摘要： There is provided a radar device with which the density of transmitted signals can be made uniform in relation to orientation even if the rotation rate of an antenna fluctuates, and interference removal processing can be given a simpler configuration. A radar device that transmits and receives signals while rotating an antenna comprises a motor, a transmission pulse generator, and a transmitter. The motor rotates the antenna (antenna main body). The transmission pulse generator generates transmission timing pulses for transmission signals from the antenna based on the rotational angle of the antenna main body. The transmitter transmits transmission signals via the antenna according to the transmission timing pulses generated by the transmission pulse generator.

摘要： A radar signal processing device is provided, which performs a scan correlation in a polar coordinate system to secure accuracy of the scan correlation, and prevents a suppression of a target object moving at high speed due to the scan correlation. A polar coordinate correlator performs, in a polar coordinate system, a correlation between reception data and previous correlated data stored in a previous data storage. A trend curve calculating module calculates a trend curve of a distance-direction signal level of the reception data in the polar coordinate system. A target detecting module detects a target based on the signal level of the reception data and the trend curve. Further, the polar coordinate correlator changes the contents of the correlation of the reception data based on the target detection result from the target detecting module.

摘要： An echo image generating device may be provided, which includes a signal acquiring module, a sensitivity setting module, and a screen generating module. The signal acquiring module may acquire an echo signal from a target object around a ship. The sensitivity setting module may perform a first sensitivity setting for the echo signal in a first range, and a second sensitivity setting for the echo signal in a second range without including the first range, the second sensitivity setting being different from the first sensitivity setting. The screen generating module may generate an echo image of the first range based on the first sensitivity setting, and generate an echo image of the second range based on the second sensitivity setting.
