< ul>1, the working principle of radar: 1. The radar FM transmitter generates sufficient electromagnetic induced kinetic energy, which is transmitted to the antenna through the transceiver switch. The antenna radiates this electromagnetic induced kinetic energy into the air body, concentrating it in a narrow location to create a beam that propagates forward. After the electromagnetic wave hits the target in the beam, it will be reflected in all directions, in partThe azimuth of the electromagnetic induced kinetic energy reflected back to the radar is obtained from the radar antenna. 2, the working principle of radar is: using the time difference between the transmitted pulse and the received pulse, multiplied by the propagation speed of electromagnetic waves, the speed of light, so as to obtain the precise distance between the radar and the target. A device that uses very short radio waves for detection.
3, the principle of radar is to detect and locate targets by transmitting and receiving radio waves. A radar system sends radio waves through an antenna. These radio waves travel through the air at the speed of light. Radio waves emitted by radar can be continuous orPulsed, depending on the type of radar and application scenario.
4. The radar measures the precise distance to the target by transmitting the pulse and receiving the difference in time when it is reflected back. Radar uses extremely short radio waves for detection, which bounce back when they encounter obstacles. Radar determines the direction, distance, size and other attributes of the target according to the principle of radio wave reflection. The received radio waves are displayed on the indicator, providing an image of the detected target.
5. Radar equipment transmits electromagnetic wave energy through an antenna and points it in a specific direction. When the object is in this direction, it willReflect these electromagnetic waves. The radar antenna picks up these reflected waves and transmits them to the receiving device for processing. The receiving device extracts information about the object, such as its location.
1, EDGE is a data transmission technology based on GSM and GPRS networks, which significantly improves the data transmission rate by improving the coding scheme and using higher order modulation methods, while maintaining compatibility with the existing GSM network. Compared to GPRS, EDGE can provideHigher data transfer speeds, allowing users to download web pages, pictures, and files faster.
2, EDGE is the abbreviation of Enhanced Data Rate for GSM Evolution, that is, enhanced data rate GSM evolution technology. EDGE is a transition technology from GSM to 3G and can be seen as a 5G network. It mainly adopts a new modulation method in the GSM system, that is, the most advanced multi-slot operation and 8PSK modulation technology.
3, EDGE network introduction: EDGE is the enhanced data rate GSM evolution technology. It is a transition technology from GSM to 3G, which mainly adopts a new modulation method in the GSM system, that is, the most advanced multi-slot operation and 8PSK modulation technology.

4, the display E at the top of the phone usually refers to the network type of 2G, that is, Edge network. Because of the slow speed of this network, it is recommended not to carry out large traffic data transmission during use, otherwise it may cause network stalling orIntermittent connection condition. When the top of the phone shows E, it may also mean that the phone's signal is weak. At this time, you need to leave the indoor or electronic equipment concentration area, and go to the open place to get a better signal.
5, EDGE is a network technology, it is one of the important technologies from GSM to 3G transition. EDGE technology significantly improves data transfer rates by employing advanced modulation methods such as multi-slot operation and 8PSK modulation technology. The Microsoft Edge browser uses open source code on both mobile and desktop, contributing to the open source community.
6, EDGE is a mobile network technology between 2G and 3G, its full name is Enhanced Data rates for GSM Evolution, that is, enhanced data rate GSM evolution technology. It offers a higher data transfer rate than traditional GPRS, but is still lower than 3G and 4G speeds. When an Apple phone displays EDGE, it indicates that the mobile network the phone is currently connected to is the EDGE network, and not the faster 3G, 4G or 5G network.
2. Now 3G is running in some places.CDMA belongs to the telecom company can go to the local business hall of telecom, the downlink rate is generally about 140K; The mobile is EGPRS, also known as EDGE, and the downlink rate is generally about 250K.
4, the main difference is speed. Mobile GPRS actual speed: basically and 56Kbps Modem speed is the same. The actual speed, called 2G network Mobile EDGE, is 230Kbps, the fastest of the three. EDGE, known as 75G Network Mobile, is backward compatible with GPRS and automatically switches to D where the signal is good
