FFT (Fast Fourier transformation) is a classic algorithm used for digital signal processing. Many people who have studied DSP or chip design know this algorithm. However, have you ever wondered why there are so many FFT operations in digital signal processing? Some may say that in order to analyze the signal spectrum. The problem below is to analyze the daily needs of the spectrum, such as mobile phone calls, radar measurement speed and direction, and

Http://forum.unity3d.com/threads/44911-2-cameras-running-the-same-time 1: Two camera instances are displayed on one screen at the same time. It is certainly possible to have multiple cameras at once. There are a couple things to know that will help with this: -Cameras have a "depth" property. This determines which orderCameras will draw. The camera with the highest depth will draw on topOf the camera with the lowest. -Clear flags are important when dealing with multiple cameras. ThisBasi

Data Distribution Management Data Distribution Management is based on some requirements in simulation. For example, in the air defense simulation, the ground radar only needs to know the air condition data within a certain range, therefore, the simulation members of the aircraft only need to transmit the data in the specified region to the radar members according to the data requirements of the ground

: Cartographer[2] and cartographer_ros[3]. Cartographer is primarily responsible for processing data from radar, IMU and odometer and building maps based on these data, which is the cartographer theoryThe underlying implementation. Cartographer_ros is based on the ROS communication mechanism to obtain the sensor data and convert them into cartographer defined in the format passed to cartographer processing, at the same time the cartographer processing

-Proof tires will eventually reach a reasonable stage. ●Reversing radar The reversing radar is a safety auxiliary device for parking or reversing cars. It can provide sound or a more intuitive display to inform drivers of obstacles, the problems caused by the visits between the left and right sides of the driver's parking, reversing, and starting vehicles are eliminated, and the defects of blind spots and

extensible modules are as follows: * Radar module-Basic Radar Image Processing; * OrthoBase-corrected the positive injection of regional digital images; * OrthoBASE Pro-Fast Normal shooting correction for aerial and Wei films, and automatic extraction of High Precision DEM Using stereo images; * OrthoRadar-supports correction of RadarSat and ERS radar images; *

Each of small island was a point locating in the sea side. and any radar installation, locating on the coasting, can only coverD distance Can be covered by a RADIUS installation, if the distance between them are atmostd .We use Cartesian coordinate system, defining the coasting is the x -axis. The sea side is abovex -axis, and the land side below. Given

I. Overview of Chart.jsChart.js Introduction-Chart.js is a simple, object-oriented, designer and developer-Ready Chart Drawing Tool Library-Official Address: http://www.chartjs.org/Chart.js Features-Based on HTML 5-Chart.js is based on HTML5 Canvas technology, supports all modern browsers, and offers a downgrade alternative for IE7/8-Simple and flexible-Chart.js does not rely on any external tool library, lightweight (only 4.5k after compression), and provides methods for loading external parame

of reflection. It is divided into two types: gas-medium and water-medium. The air-Medium is a sound-wave transmission medium, the transducer is placed above the water surface, reflected by the surface acoustic waves, according to the echo time can be calculated and show the water level. The instrument does not touch water body, completely free from the water sediment, velocity impact and aquatic plants and other adverse factors. The Shu Jie is to mount the transducer at the bottom of the river

and me Planes in air combat. After the British invented the radar, they found a big problem in application: on the radar screen, they couldn't figure out which planes are enemies and who are themselves. As a result, they installed the identification system (identificationfriendorfoe, IFF) on the plane and installed the corresponding identification device (secondary rad
