A structure evaluation apparatus has an acquisitor and an evaluator. The acquisitor acquires a distribution that represents a distribution of strength of a reflected wave obtained by an electromagnetic radar scan to a reinforced concrete which comprises concrete and a material other than concrete. The evaluator calculates similarity, with reference to a reference region including the material in the distribution, of other regions including the material than the reference region in the distribution.

This disclosure provides an information display device, which includes a sensor signal acquirer for acquiring a sensor signal indicating a content detected by a sensor, a signal processor for performing first signal processing and second signal processing different from the first signal processing, on the sensor signal, and a display unit for displaying on a screen image, first information of the sensor signal after the first signal processing, and partial information of second information of the sensor signal after the second signal processing in a different display mode from the first information, the partial information being different from the first information.

A heads up display arrangement for a motor vehicle includes a wheel sensor sensing a speed of rotation of a wheel. A distance-sensing device senses a distance between the motor vehicle and an other vehicle that is in front of the motor vehicle relative to a direction of travel of the motor vehicle. A processor receives the sensed speed of rotation of the wheel and calculates dependent thereon a stopping distance of the motor vehicle. A heads up display presents an image indicative of both the calculated stopping distance of the motor vehicle and the sensed distance between the motor vehicle and the other vehicle.

Various embodiments of the present technology generally relate to detecting and manipulating radar image data. More specifically, some embodiments relate to systems, methods, and computer-readable storage media for detecting, processing, viewing, and manipulating radar images in an image viewer application. Radar image data captured by a radar imaging system, such as a synthetic aperture radar (SAR) or other satellite-based equipment, comprises data unreadable by image viewers. In an implementation, an open-source plug-in for an image viewer application obtains SAR data, performs one or more algorithms on the SAR data to detect an image, and provides the detected image to an image viewer for display on a graphical user interface. Further, requests for manipulation of the detected image made by the image viewer application may be performed by the plug-in and exported in complex data formats for use downstream.

According to one embodiment, a system includes a radar and a controller. The radar includes at least one first antenna and at least one second antenna. The at least one first antenna transmits a first transmission wave at a first time and transmits a second transmission wave at a second time different from the first time. The at least one second antenna receives reflected waves of the first transmission wave and the second transmission wave.

The disclosed radar system may include a radar mechanism comprising a transmitter and at least one receiver. The radar system may also include a signal generator that generates a frequency-modulated radar signal. In addition, the radar system may include a delay mechanism that (1) receives the frequency-modulated radar signal from the signal generator and (2) after a certain period of delay, passes the frequency-modulated radar signal to the transmitter to be transmitted to a transponder located on a wearable artificial reality device. The radar system may also include a processing device that (1) receives the frequency-modulated radar signal from the signal generator, (2) detects a signal returned to the receiver from the transponder, and (3) calculates a distance between the transponder and the receiver based at least in part on an analysis of the signal returned from the transponder and the frequency-modulated radar signal received from the signal generator.

A radar device includes a transmitter, a receiver and processing circuitry. The transmitter transmits a first pulse signal and a second pulse signal, a pulse width of the second pulse signal being wider than a pulse width of the first pulse signal. The receiver may receive a first reception signal including a reflection signal of the first pulse signal and a second reception signal including a reflection signal of the second pulse signal. The processing circuitry may be configured to compare, in a first section that is at least partly in a distance direction, a signal intensity of the first reception signal with a signal intensity of the second reception signal, and generate a display signal based on a result of the comparison.

A weather radar module includes a memory, a vertical weather display, and a processor. The vertical weather display is configured to display weather in a vertical format. The processor is configured to control a radar antenna of the aircraft to perform a sweep in the horizontal direction and receive horizontal sweep radar returns, determine first weather parameters of a weather model in the vertical format based on the horizontal sweep radar returns, and store the first weather parameters in the memory. The processor is further configured to provide an estimate of the weather in the vertical format based on fusing vertical weather data, which is based on the vertical sweep radar returns, with the first weather parameters in the memory or with vertical display data based on the first weather parameters, and cause the vertical weather display to display the estimate of the weather in the vertical format.
