What are the functions of a reconnaissance satellite? What are the types of reconnaissance satellite

Military espionage public security reconnaissance satellite information is generally not disclosed to the public, I have personally experienced being killed by the black police, I know that the satellite can clearly see everything inside and outside the earth, can eavesdrop on indoor and outdoor sounds, can monitor and intercept **, and can lock people in satellite positioning at the same time, please search for fugitives and residential surveillance.

What is a reconnaissance satellite? How important is it in aviation? Listen to the expert's analysis.

There are four types of military reconnaissance satellites in terms of performance.

1. Photographic reconnaissance satellites. It is mainly equipped with visible light cameras, including panoramic scanning cameras for census purposes and format cameras for detailed surveys. Some of the sealed capsule taken by satellites are directly sent back to the ground for washing and interpretation, and there are only 3 countries in the world that have mastered this technology.

In order to prevent the ** cabin from falling into the hands of others, a self-detonation device will be installed on it, and it will be blown up by itself as soon as the specified time has passed.

Another method is radio transmission, which is to automatically flush out the photographed ** on the satellite, and then convert the target image into an electrical signal, send it to the ground in the form of radio waves, and then restore it to the target image. Some photographic reconnaissance satellites are equipped with television cameras, and while conducting reconnaissance of ground targets, they send information to the ground command center, which is faster and easier.

2. Electronic reconnaissance satellites. It is equipped with reconnaissance receivers and tape recorders, which are mainly used to reconnoiter the location and frequency of radar and military radio stations, and sometimes intercept telemetry signals sent during missile tests to grasp the development of the opponent's strategy.

Electronic reconnaissance satellites are superior and safe compared to other electronic reconnaissance means, but their weakness is that when there are too many radars or radio stations on the ground, and the signals are too dense and too mixed, it is difficult to screen out truly useful information, and they are also easily deceived and jammed by false signals. If ground-based radars and radios are temporarily turned off, they can also evade their detection.

3. Missile early warning satellites. Used to guard against missile attacks. ICBMs fly fast, have high ballistic ranges, and have a long range, and can hit targets of 8,000 to 13,000 kilometers in about 30 minutes after launch.

4. Marine surveillance satellites. It is specially designed to monitor the activities of surface ships and underwater submarines. Such satellites equipped with electronic reconnaissance equipment are no different from electronic reconnaissance satellites; Equipped with radar equipment, it can actively search for targets and discover targets without relying on signals transmitted by the other side.

Foreign countries are experimenting with marine surveillance satellites equipped with infrared detectors, and it is envisaged that nuclear submarines can be reconnoitred from an altitude of several hundred miles to a depth of 60 meters.

Because of its advantages, reconnaissance satellites have the advantages of a large reconnaissance area, a wide range, a high speed, good results, and the ability to monitor a certain area on a regular or continuous basis without being restricted by national borders and weather.

It is equipped with four microwave remote sensing instruments and a visible and infrared scanning radiometer, i.e., synthetic aperture side-looking radar, altimetry radar, radar scatterometer, microwave radiometer and visible and infrared radiometer, to monitor a large area of the ocean. Unfortunately, the good times did not last long, 3 months later.

Reconnaissance satellites can be divided into four categories according to their use: photographic reconnaissance satellites, electronic reconnaissance satellites, missile early warning satellites, and maritime surveillance satellites.

Satellite reconnaissance, because satellite reconnaissance covers a large area, is not limited by national borders and geographical conditions, and is fast in reconnaissance, and provides accurate and reliable intelligence, satellite reconnaissance has become an important part of the military's main military intelligence and operational command system. At present, reconnaissance satellites are mainly divided into electronic reconnaissance satellites, military imaging satellites, missile early warning satellites, maritime surveillance satellites, and nuclear detection satellites. For important targets, reconnaissance satellites can maintain operations over them one to two times a day.

During the Gulf War, the United States and its multinational forces used about 37 military satellites for reconnaissance in outer space, involving 12 US military satellite systems and some civilian communications and remote sensing satellite systems. Among them, there are 18 reconnaissance satellites of five types for the US military in the Gulf region, which constitute a huge satellite monitoring network in outer space, which can keep abreast of the movements and changes in the deployment of the Iraqi forces and the results of air strikes against Iraq, and provide accurate and reliable intelligence to the multinational forces.

Reconnaissance satellites.

Satellites' optical and electrical remote sensors or radio receivers and other reconnaissance equipment are used to collect relevant information on ground, sea, and air targets from orbit to carry out reconnaissance, surveillance, and tracking of targets, and to obtain intelligence. The electromagnetic wave information collected by the reconnaissance equipment is stored in the return capsule by film, tape and other records, and sent to the ground receiving station for processing on the earth** or through radio transmission methods to obtain intelligence from it.

It has the advantages of large detection area, wide range, fast speed, good effect, long-term or continuous surveillance, and is not restricted by national borders and geographical conditions. According to the different tasks and reconnaissance equipment performed, they are generally divided into photographic reconnaissance satellites, electronic reconnaissance satellites, marine monitoring satellites, and missile early warning satellites.

acd。The quality he can see by satellites?

I really admire these two teachers.

Hello? I'm going to be when your class grows up? I'm angry, oh oh oh. When your class grew up, the sky has seen it, oh oh oh oh okay good night, good night? Oh oh oh
