A method and system are disclosed for tracking a remote vehicle which is driving in a lateral position relative to a host vehicle. Target data from two radar sensors are provided to an object detection fusion system. Wheels on the remote vehicle are identified as clusters of radar points with essentially the same location but substantially varying Doppler range rate values. If both wheels on the near side of the remote vehicle can be identified, a fusion calculation is performed using the wheel locations measured by both radar sensors, yielding an accurate estimate of the position, orientation and velocity of the remote vehicle. The position, orientation and velocity of the remote vehicle are used to trigger warnings or evasive maneuvers in a Lateral Collision Prevention (LCP) system. Radar sensor alignment can also be calibrated with an additional fusion calculation based on the same wheel measurement data.

Disclosed are devices, systems and methods for managing parking monitoring and enforcement. In one aspect, a method of determining whether a vehicle is present in a parking space includes monitoring the parking space with a first vehicle detection technique utilizing image processing and monitoring the parking space with a second vehicle detection technique that does not utilize image processing. The parking space can be monitored with a third vehicle detection technique that is different than the first and second vehicle detection techniques. A conclusion that a vehicle has entered or left the parking space can be determined upon a agreement of the multiple techniques employed.

A wireless power transmitting device is provided. The wireless power transmitting device may comprise an antenna, a memory, and a processor configured to control to store, as reference information, information of a first reflected signal of a pilot signal sent out through the antenna at a first time in the memory and control to compare the reference information with information about second reflected signals of a pilot signal sent out through the antenna at a second time, and determine a position of a target for detection based on a result of the comparison.

According to an embodiment a wireless power transmitting device, includes a power transmission antenna including patch antennas to wirelessly transmit power, and communication antennas configured to receive a communication signal from an electronic device. The wireless power transmitting device also includes a processor configured to detect a direction in which the electronic device is positioned based on the communication signal received through the communication antennas and control the power transmission antenna to transmit the power in the detected direction.

A handheld device, an object positioning method thereof and a computer-readable recording medium are provided. The handheld device includes a radar sensor, an image sensor and a control unit. The radar sensor emits a detection wave, and receives a reflected wave generated by an object by reflecting the detection wave. Each object generates one of the reflected waves. The image sensor captures an image. The image includes a subset of the objects. The control unit extracts a waveform signature of each reflected wave, recognizes the waveform signature in a time domain and a frequency domain to determine a first type of each object, obtains a first position of the object according to the reflected wave, obtains a second type and a second position of each object according to the first image, and performs object mapping to combine or compare the first position and the second position of the object.

Using communication unit positional information acquired using infrastructure communication and moving body positional information detected using millimeter-wave radar, a moving body existing in a blind spot of a radar detection region is recognized, and behavior is predicted from movement information of the moving body, by deleting the moving body information detected by millimeter-wave radar from the communication unit information acquired using infrastructure communication.

Embodiments for a terrain following (TF) radar configured for use in an airborne system are generally described herein. In some embodiments, a radar return comprising dual polarimetry radar data is processed to determine a Correlation Coefficient (CC), a Differential Reflectivity (ZDR), and a Specific Differential Phase (KDP). Discriminator logic is applied to the CC, the ZDR and the KDP to determine whether the radar return comprises solely rain. Further signal processing may be performed on the radar return when the radar return does not comprise solely rain. When the radar signal comprises solely rain, the radar return is tagged as a rain return. Applying the discriminator logic may include applying linear and/or quadratic functions to the CC, the ZDR and the KDP to determine whether the radar return comprises solely rain.

At least one object having a risk of collision with the vehicle is detected. Levels of autonomous control are transitioned in response to detection of a potential collision based at least in part on an autonomous peril factor which includes a probability of collision and a magnitude of possible damage in the event of a collision.

Provided are methods of using electromagnetic waves for detecting metal and/or dielectric objects. Methods include directing microwave and/or mm wave radiation in a predetermined direction using a transmission apparatus, including a transmission element; receiving radiation from an entity resulting from the transmitted radiation using a detection apparatus; and generating one or more detection signals in the frequency domain using the detection apparatus. Methods may include operating a controller, wherein operating the controller includes causing the transmitted radiation to be swept over a predetermined range of frequencies, performing a transform operation on the detection signal(s) to generate one or more transformed signals in the time domain, and determining, from one or more features of the transformed signal, one or more dimensions of a metallic or dielectric object upon which the transmitted radiation is incident. A system and method for remote detection and/or identification of a metallic threat object using late time response (LTR) signals is also disclosed.

When large vehicles and small vehicles travel together in a mine, they are distinguishedly detected. On a haulage vehicle for a mine, a first obstacle detection device and a second obstacle detection device are disposed. The obstacle detection devices are disposed so that they have detection directions oriented in a same direction in horizontal planes, respectively. The first obstacle detection device 111 is disposed at a height where it can detect each small vehicle, while the second obstacle detection device 112 is disposed at a height where it can detect each large vehicle without detection of any small vehicle. On the basis of detection results of the first obstacle detection device 111 and second obstacle detection device 112, a detection processing device 120 determines whether an object is a small vehicle or a large vehicle.
