UAV detection radarManufacturers believe that radar is an electromagnetic sensor used to detect and locate reflecting objects. The radar emits electromagnetic waves to irradiate the target and receives its echo, so as to obtain the distance, radial velocity, azimuth, altitude and other information from the target to the electromagnetic wave emission point. The advantage of radar is that it can detect long-distance targets day and night without being blocked by fog, clouds and rain. It has the characteristics of all-weather and all-weather, and has a certain penetration ability. Therefore, radar is not only an indispensable electronic equipment in the military, but also widely used in social and economic development and scientific research.
UAV detection radarManufacturers believe that during World War II, radar began to appear in military applications. By deploying radars along the English Channel in England, German aircraft could be spotted in advance and eventually won the British air war. At this time, the radar has only basic functions such as distance and azimuth detection.
UAV detection radar manufacturers believe that after the Second World War, radar has developed new radar systems, such as monopulse angle tracking, pulse Doppler signal processing, high-resolution synthetic aperture and pulse compression, combined systems with IFF, Computer automatic fire control system, terrain avoidance and terrain following, passive or active phased array, frequency agility, multi-target detection and tracking, etc.
UAV detection radarThe manufacturer believes that with the scientific progress in the fields of microelectronics and the continuous development of radar technology, its connotation and research content are also expanding. The specific purpose and structure of various radars are different, but the basic framework is basically the same, including transmitters, transmitting antennas, receivers, receiving antennas, processing parts and displays, as well as auxiliary equipment such as power supply equipment, data acquisition equipment, and anti-jamming equipment.
UAV detection radarManufacturers believe that in the field of radar, band codes are generally used to identify the commonly used operating frequency bands of radar. At present, the working frequency band of radar is generally limited to 0.003GHz(HF band) ~ 110GHz (W band), and the terahertz field above 110GHz is still in the exploration and research stage. Each band has its own unique properties, which make it more suitable for certain applications than other bands. For example, the S-band is significantly affected by rain clutter, and long-range weather radar, which needs to accurately estimate the rainfall rate, is the first frequency of choice. Generally speaking, under the same conditions, the lower the radar operating frequency band, the wider the antenna beam, and the lower the measurement accuracy, which is more suitable for rough search of a large number of targets in a large range; the higher the operating frequency band, the narrower the antenna beam, and the higher the measurement accuracy. It is more suitable for accurate tracking of a small number of targets in a small range.
UAV Detection Radar ManufacturersRadar is a kind of complex electronic equipment, and the progress of science and technology in related fields has promoted the development of radar technology. Therefore, there are many methods according to the technical system, and each method highlights the outstanding characteristics of radar in one or several technical aspects.
