摘要： A plurality of images can be acquired from a plurality of sensors and a plurality of flattened patches can be extracted from the plurality of images. An image location in the plurality of images and a sensor type token identifying a type of sensor used to acquire an image in the plurality of images from which the respective flattened patch was acquired can be added to each of the plurality of flattened patches. The flattened patches can be concatenated into a flat tensor and add a task token indicating a processing task to the flat tensor, wherein the flat tensor is a one-dimensional array that includes two or more types of data. The flat tensor can be input to a first deep neural network that includes a plurality of encoder layers and a plurality of decoder layers and outputs transformer output. The transformer output can be input to a second deep neural network that determines an object prediction indicated by the token and the object predictions can be output.

摘要： A method for adaptively selecting a ground penetrating radar (GPR) image for detecting a moisture damage is provided. The method adaptively selects the GPR image according to a contrast of the GPR image. The method includes the following steps: S1, reading pre-processed GPR data; S2, adjusting a resolution of a picture; S3, inputting a data set into a recognition model; S4, outputting a moisture damage result; S5, judging whether there is a detection target or not by using an initial random image data set; and S6, generating the GPR image randomly incrementally and selecting the GPR image with a proper contrast. A proper B-scan image is found effectively, quickly and automatically by combining a recognition algorithm and a deep learning model or an image classification model to achieve an automatic recognition and detection based on the GPR image and improving a recognition precision as well.

摘要： Systems, devices, and methods related to a radar and an artificial neural network are described. For example, the radar can have at least one processing unit configured to execute instructions implementing matrix computation of the artificial neural network. The artificial neural network is configured to identify features in the radar image in an output responsive to an input containing a radar image. Optionally, the radar can further include an image sensor to generate an optical image as part of the input to artificial neural network. Instead of outputting the radar images and/or the optical images, the radar may output a description of the features identified via the artificial neural network from the radar image.

摘要： Fly eye radar is integration of holographic simultaneous wide covering non-scanning system with monopulse high directional accuracy method of multi-beam multi-axis fast signals processing for imaging application. Radar system with multi-beam multi-axis overlap antenna patterns with staring, not scanning continuous wide covering area allow to receive maximum non-interrupting information from multiple objects. Multi-axis 3D object observation provides high-resolution and high probability objects recognition. High-speed object imaging providing by simultaneous multi-channel signals processing with one-step algorithms and reference signals from overlap antennas. Digitizing of reflected signals directly on each directional antenna allows distribution of radar modules around carrier vehicle or swarm of vehicles. Transformation and processing of received signals in time domain, frequency domain and multi-axis space domain provides additional possibility to enhance image resolution and object recognition.

摘要： A radar antenna suitable for a drone is provided, which is able to compensate for the agility of drone motion. The radar antenna contains a sandwich of two printed circuit boards between three conductive plates. A first printed circuit board comprises a preferably circular array of first antenna elements such as dipoles. A second printed circuit board, parallel to the first printed circuit board, comprises an array of second antenna elements. One of the array of first antenna elements and the array of second antenna elements is an array of transmission antenna elements and the other an array of reception antenna elements. The first printed circuit board is located below the second printed circuit board. Three conductive plates are used to shape the antenna patterns from the antenna elements so that the main lobes of the antenna patterns are directed obliquely downwards and the antenna patterns from the different array at least partly overlap, suppressing vertical side lobes. A first conductive plate separates the first and second printed circuit boards. A second conductive plate is located above the second printed circuit board, extending radially outward beyond the first conductive plate. A third conductive plate is located below the first printed circuit board. The first conductive plate extends radially outward beyond the third conductive plate.
