摘要： A system and method for detecting and avoiding a collision includes measuring speed of one or more vehicles and at least one parameter indicating road surface and condition, weather, and tire pressure. Rear image dimensions are proportional to the speed of the trailing vehicle and front image dimensions are proportional to the speed of the index vehicle. The timing of the projected images will allow for safe deceleration of trailing and of the index vehiclesThe images are projected either as flat images on the roadway or three-dimensional (holographic) images. The occurrence and severity of a collision is defined by the rate of change in dimensions of the projected images that exceeds a predetermined value corresponding to a deceleration or acceleration of more than 1.1 g. Collision data measured by vehicle or extra vehicular (such as GPS) sensors are instantly stored and transmitted to the police department and emergency medical services.

摘要： In some examples, a system is configured to determine a reliability index for weather information received by a weather system. The reliability index may indicate a degree of confidence of the accuracy of the weather information. For example, a system may determine a weather product for each of one or more voxels of a plurality of voxels in a three-dimensional or four-dimensional volumetric buffer, and based on a combination of the weather product and the weather information, determine a reliability index for the weather product. The system may display a first visual representation of the weather product and a second visual representation of the corresponding reliability index.

摘要： System and method for estimating locations and range rates of a multiplicity of targets by estimating range-Doppler state representation, including: computing a prior range-Doppler state estimate matrix and a measurement matrix containing phase shifted and re-ordered samples of a transmitted signal waveform; applying the measurement matrix to the range-Doppler state estimate matrix to generate a prediction of a current return sample and calculating a difference between the current return signal sample and the prediction of the current return signal sample; multiplying the difference by a gain matrix to obtain an adjustment to the prior range-Doppler state estimate matrix; repeating the process for a next return signal; computing an estimated range-Doppler map (RDM); applying a threshold to the estimated RDM to detect individual targets and obtain their range and Doppler parameters; and using the range and Doppler parameters to estimate the locations and range rates of the targets.

摘要： An image processing device which generates an image where a target object can be discriminated from an object other than the target object. An image processor (15), for echo signals read from a sweep memory (14), calculates a ratio of echo signals indicating a predetermined level or higher among the echo signals of a predetermined number of samples, and generates image data having a display element according to the calculated ratio. This ratio indicates a lower value for an object more isolated and a higher value for an object existing as a larger mass. The image processor (15)acquires color values according to the calculated ratio. Since the target object, such as a ship, is an isolated object and the ratio becomes low, the color values indicate red, and since inland is an object existing as a large mass and the ratio becomes high, the color values indicate green.

摘要： A radar or sonar system amplifies the signal received by an antenna of the radar system or a transducer of the sonar system is amplified and then subject to linear demodulation by a linear receiver. There may be an anti-aliasing filter and an analog-to-digital converter between the amplifier and the linear receiver. The system may also have a digital signal processor with a network stack running in the processor. That processor may also have a network interface media access controller, where the system operates at different ranges, the modulator may produce pulses of two pulse patterns differing in pulse duration and inter-pulse spacing, those pulse patterns are introduced and used to form two radar images with the two images being derived from data acquired in a duration not more than twenty times larger than the larger inter-pulse spacing, or for a radar system, larger than one half of the antenna resolution time. One or more look-up tables may be used to control the amplifier. The radar system may generate digital output which comprises greater than eight levels of radar video.

摘要： A radar device is disclosed, which includes an antenna for transmitting an electromagnetic wave and receiving an echo signal from a target object while rotating in a horizontal plane, a display module for displaying the target object so as to correspond the echo signal to a position of the target object with respect to the antenna, a speed calculation module for calculating a relative velocity of the antenna and the target object, and a risk level detection module for detecting a risk level of the target object based on the relative velocity of the target object calculated by the speed calculation module. The speed calculation module calculates the relative velocity of the target object based on a change in phases of at least two of the echo signals received at a different time. The display module controls a display mode of the target object based on the risk level.
