    摘要: A radar includes a transmitter antenna unit that includes multiple transmitter antennas arranged at first horizontal distances and first vertical distances from each other, a receiver antenna unit that includes multiple receiver antennas arranged at second horizontal distances and second vertical distances from each other, a transceiver that transmits transmission signals through the transmitter antenna unit and receives return signals reflected from a target object trough the receiver antenna unit, and a processing unit that derives information about the target object by processing the received return signals.

    摘要: There is provided a radar device which detects targets by performing a signal processing procedure based on a frequency-modulated continuous wave and the reflected waves of the transmission wave from the targets. A signal processing unit is configured to periodically perform the signal processing procedure based on beat signals which are differential waves between the transmission wave and the reflected waves. A monitoring unit is configured to monitor each of processing states of processes which are sequentially performed in the signal processing procedure. A changing unit is configured to change a processing condition for the subsequent-stage processes of a process, according to the processing state of the process, if the monitoring unit detects that the process is in a high load state, from the processing states.

    摘要: A vehicle, radar system and method of determining an angle of arrival of an object is disclosed. A radar array generates a linear frequency modulated source signal and includes a first channel and a second channel for receiving a reflection of the source signal from the object. A processor obtains a channel response for the first radar channel and for the second radar channel over a bandwidth of the source signal, partitions the frequency band into a plurality of frequency sub-bands, determines a variation between the first and second channel responses for a selected frequency sub-band, receives a reflection of the source signal at the first channel and at the second channel, corrects at least the second channel within the frequency sub-band using the determined variation, and determines an angle of arrival for the object based on the correction within the frequency sub-band.

    摘要: A building radar-camera system includes a camera configured to capture one or images, the one or more images including first locations within the one or more images of one or more points on a world-plane and a radar system configured to capture radar data indicating second locations on the world-plane of the one or more points. The system includes one or more processing circuits configured to receive a correspondence between the first locations and the second locations of the one or more points, generate a sphere-to-plane homography, the sphere-to-plane homography translating between points captured by the camera modeled on a unit-sphere and the world-plane based on the correspondence between the first locations and the second locations, and translate one or more additional points captured by the camera or captured by the radar system between the unit-sphere and the world-plane based on the sphere-to-plane homography.

    摘要: Method of automatic target angle tracking by sum-and-difference monopulse radar covers radiolocation sphere and specifically monopulse direction finding systems. It can be used in order to increase guidance accuracy, for example, for anti aircraft missiles and of unmanned aerial vehicles to radar targets such as: radio beacons; aerial vehicles reflecting the radio signal that illuminates them; aerial vehicles and ground-based devices radiating radio signals and jamming signals. The aim of the method consists in the assurance of reliability and stability and in the enhancement of guidance accuracy of automatic target angle tracking due to elimination of automatic tracking losses and great errors arising during the influence of the signals of orthogonal polarization or polarization close to it.The proposed method provides full protection from polarization jamming for all types of monopulse radars.

    摘要: A scanning method of an in-vehicle scanning-type radar for emitting beams subsequently to execute scanning and for detecting an object includes determining whether or not the object is in an approaching state. When it is determined that the object is not in the approaching state, executed is a first scanning for scanning within a first angle range. When it is determined that the object is in the approaching state, executed is a second scanning for scanning within a second angle range that is narrower than the first angle. A period during which the radar scans the second angle range once in the second scanning is shorter than that during which the radar scans the first angle range once in the first scanning.
