Description

Anti-interference radar of simple and easy dismouting

Technical Field

The utility model relates to a radar installations's technical field especially relates to an anti-interference radar of simple and easy dismouting.

Background

Radar, a transliteration of radio in english, is derived from the acronym of radio detection and ranging, and means "radio detection and ranging", i.e. finding objects and determining their spatial positions by radio. Therefore, radar is also referred to as "radiolocation". Radars are electronic devices that detect objects using electromagnetic waves. The radar emits electromagnetic waves to irradiate a target and receives the echo of the target, so that information such as the distance from the target to an electromagnetic wave emission point, the distance change rate (radial speed), the azimuth and the altitude is obtained.

The specific use and structure of various radars vary, but the basic form is consistent, including transmitters, transmit antennas, receivers, receive antennas, processing sections, and displays. And auxiliary equipment such as power supply equipment, data recording equipment, anti-interference equipment and the like.

The radar functions similarly to the eyes and ears, and of course, it is no longer a natural task, and its information carrier is a radio wave. In fact, whether visible light or radio waves are essentially the same thing, they are electromagnetic waves, and the speed of propagation in a vacuum is the speed of light C, the difference being that their respective frequencies and wavelengths are different. The principle is that a transmitter of radar equipment emits electromagnetic wave energy to a certain direction of space through an antenna, and an object in the direction reflects the contacted electromagnetic wave; the radar antenna receives this reflected wave and sends it to a receiving device for processing and extracting certain information about the object (distance of the target object to the radar, rate of change of range or radial velocity, azimuth, altitude, etc.).

The principle of measuring speed is the frequency Doppler effect generated by relative motion between the radar and a target. The target echo frequency received by the radar is different from the radar transmitting frequency, and the difference between the target echo frequency and the radar transmitting frequency is called Doppler frequency. One of the main information that can be extracted from the doppler frequency is the rate of change of range between the radar and the target. When a target and an interference clutter exist in the same spatial resolution unit of the radar at the same time, the radar can detect and track the target from the interference clutter by using the difference in doppler frequency between them. The principle of measuring the target azimuth is to utilize the sharp azimuth beam of the antenna and to measure the elevation angle beam with narrow elevation angle, so as to calculate the target height according to the elevation angle and the distance. The principle of measuring distance is to measure the time difference between the transmitted pulse and the echo pulse, and the electromagnetic wave is transmitted at the speed of light, so that the time difference can be converted into the accurate distance between the radar and the target.

The radar of small dimension is fixed and has more installation steps on the earth's surface, proposes the anti-interference radar of a simple and easy dismouting earlier, makes things convenient for the staff to install the adjustment to it fast.
