20080266169 | RADAR DEVICE - A radar device capable of detecting a target object by itself only in a range required by a vehicle control system by changing the detection angle depending on the distance without changing the hardware structure is provided. The radar device includes transmitting means for transmitting an electromagnetic wave as a transmission signal, receiving means for receiving the electromagnetic wave reflected from the target object as a reception signal, and signal processing means for detecting a target object existing around the vehicle from the transmission signal and the reception signal, and calculating the relative position and the relative speed between the object and the vehicle. The detection angle is changed depending on the distance for measurement, so that the target object is detected only in a region necessary in operating the vehicle control system. | 10-30-2008 |
20090033542 | GROUND CLUTTER MITIGATION USING A PARAMETRIC TIME DOMAIN METHOD - Methods and systems are disclosed for investigating a region of interest with a radar. A radar signal is propagated to the region of interest. Sampled time-domain radar data scattered within the region of interest are collected. A likelihood function is calculated with the sampled time-domain data within a parametric model of the region of interest for a defined set of parameters. The set of parameters in varied to find an extremum of the likelihood function. | 02-05-2009 |
20150102956 | Tracking Device - A targetless tracking device has a detector configured to receive scattered radiation indicative of the presence of an object. The device also has a processor which is configured to calculate a positional relationship between the device and the object based on the scattered radiation, receive an indication of a desired positional relationship to the object, and output an error signal indicative of the positional relationship versus the desired positional relationship so that the device position is able to be controlled to reduce the error signal. The processor creates first and second images at first and second points in time, respectively, and compares the first and second images in order to calculate the positional relationship. | 04-16-2015 |
20160054441 | Pre-warning Method and Vehicle Radar System - A pre-warning method utilized in a vehicle radar system is disclosed. The vehicle radar system includes a frequency-modulation continuous wave (FMCW) module, a data transceiver module and an antenna module, and the FMCW module and the data transceiver module share the antenna module. The pre-warning method includes the FMCW module utilizing the antenna to transmit and receive beat signals to detect dynamic information of a target corresponding to the vehicle radar system and obtain a first detection result, and receiving and broadcasting data to broadcast the first detection result via the data transceiver module and the antenna module, or receive a detection result broadcasted by another vehicle radar system and combine the detection result with the first detection result to perform real-time target tracking and alarm. | 02-25-2016 |
