When it comes to military radar, people often think of air-to-air intelligence radar with "high vision", airborne active phased array radar with "hearing and seeing", or anti-stealth radar with "body width and arm length", as well as ground-wave or sky-wave radar with a detection range of hundreds of thousands of meters. These radars either have fixed bases, special "mounts", or arrays with strong sense of scene... In short, extraordinary forces can be moved arbitrarily. However, do you know that there are some smaller radars that can even be carried by individual soldiers. They have played an important role in the battlefield in obscurity, and new development trends have emerged in recent years. Russia Aistyonok 1L271 portable anti-artillery radar. In the modern war, the perception of battlefield information has become the core factor determining the victory or defeat. Whoever has a large amount of information and intelligence, strong real-time and high accuracy, will be able to take the initiative in the battlefield. In order to adapt to the increasingly intense and complex battlefield environment, and timely obtain detailed information from opponents, portable battlefield reconnaissance radar came into being and became one of the key detection equipment in modern battlefield. Portable radars are generally of ultra-light design, which can be carried by infantry teams, so they are also known as mini radars. It can conduct reconnaissance and surveillance of enemy fighters, tactical vehicles and low-altitude aircraft represented by UAVs and other moving targets through plane scanning, measure their parameters such as orientation, distance and speed, judge target attributes, and provide real-time and accurate situation information for the next action. The original design goal of portable radar is to provide target information for its own artillery with its convenient and mobile characteristics. In the Gulf War, the British army equipped MSTAR radar for the front artillery observation post. This type of reconnaissance radar can be carried by two people and can be installed in three minutes. With the development and progress of science and technology, such systems gradually show the advantages of wide monitoring range, long detection distance, accurate positioning and all-weather operation. Compared with optical equipment such as infrared thermal imager, radar can work in dust, battlefield smoke, rain and other environments, showing stronger environmental applicability. The improvement of performance makes the portable radar more widely used in front line defense, urban operations, close surveillance at sea and other confrontation scenarios, and can perform various tasks such as battlefield reconnaissance, target positioning, fire calibration, wall penetration perception, etc., especially can be used for efficient search of key blocking points and potential penetration routes of the enemy, and for all-round monitoring of key targets such as bridges, roadblocks, narrow road sections. At the same time, this type of radar can also be used in border patrol, anti-terrorism operations, airport security and international peacekeeping operations. UK MSTAR portable radar. It is noteworthy that the portable radar has also emerged in recent years in the combat scenario of anti-UAV. Russia's "stab in the real" individual radar once locked the opponent's UAV system in the actual combat, showing the ability to counter new threats. The performance of portable radar has attracted many countries' strong interest in it, and some series models have been introduced, such as the AN/PS series of the United States and the FARA "headlight" series of Russia.
