RADAR DEVICE - European Patent Office - EP 2626720 B1
[0002] A radar device radiates a radio wave from a measurement point into a space and receives a signal of a reflected wave reflected from a target, to measure the distance, direction or the like from the measurement point to the target. Particularly, in recent years, a radar device has been developed that is capable of detecting a pedestrian or the like as well as an automobile as a target by ...

DIRECTION OF ARRIVAL (DOA) ESTIMATION USING CIRCULAR CONVOLUTIONAL ...
[0001] Radar systems are often incorporated into vehicle sensor systems to support various features of Autonomous Driving (AD) and/or Advanced Driver-Assistance Systems (ADAS). In some applications, a radar system is used to determine the direction of arrival (DOA) of an object in the radar field of view (FOV). In situations where multiple closely spaced objects appear simultaneously in the ...

APPARATUS AND METHOD FOR DETECTING BLOCKAGE OF AN AUTOMOTIVE RADAR ...
[0003] In automotive radar systems, it is desirable to detect when the radar sensor is blocked by debris, such as dirt, snow, ice, etc. Sensor blockage or radar blockage attenuates the transmitted and received signal such that objects in the field of view are no longer detectable. It is also important to alert the driver when the sensor is blocked so that the

Marine radar apparatus - Patent 1839071
Marine radar apparatus - Patent 1839071[0002] Marine radar generally employs a high power magnetron as a microwave source for pulsed transmitted signals. In order to reduce the amount of clutter on the radar screen caused by return signals from waves, rain and the like, the apparatus has threshold circuits set to exclude lower amplitude signals. This arrangement works satisfactorily in the ...

PHASE-CODED FREQUENCY MODULATED CONTINUOUS WAVE (FMCW) RADAR SYSTEM ...
10 [0002] Radars use radio frequency (RF) spectrum energy to detect objects or targets and find use in many fields including in ships, road vehicles and aircraft. Simply stated, a radar system includes a transmitter that transmits modulated or pulsed signals in the RF range. If the transmitted signal meets an object, it is reflected by the object and detected by a receiver. Based on ...

PEOPLE COUNTING BASED ON RADAR MEASUREMENT AND DATA PROCESSING IN A ...
(57) Various examples relate to people counting based on radar measurements. Computer-implemented example methods comprise: based on a radar measurement dataset obtained by a radar measurement of a scene, determining at least one measurement map indicative of features of one or more persons included in the scene; and processing the at least one measurement map in a machine learning or neural ...
