The early alarm concept was previously relying on large radars which cover wide areas. The threat was limited to large combat or reconnaissance aircrafts. This operational concept is still important and its threat still exists; however, a new threat has appeared within the last years. It is drones and hovercraft missiles which fly at low heights and have relatively - small radar sections.There is also the threat of remote control boats. Such threats are being rapidly produced and used while the current early alarm systems are expensive and have several gaps on wide borders. Thus, it was important to develop affordable systems which can be quickly positioned, are similar to the current systems, help to bridge the gaps, and discover the threats of drones, stealth aircrafts, hovercraft missiles, and remote control boats as a spare supporting and similar network.The Center has developed a silent radar system to deal with such developments.
The passive (silent) radar system detects any flying targets through detecting the frequency of the electromagnetic waves emitted from the civil transmission sources such as radio and television signals. This radar system detects air targets at medium and low heights. The properties of spectrum range and multiple sources of transmission and receiving provide the radar with many functions such as detecting targets with low radar section and stealth targets.
As the passive radar does not transmit any electromagnetic signals, this system can be used for hidden and secret monitoring without revealing its position and without being targeted by tracking missiles. This system can be also used for air alarm and monitoring. High energy emitted from the civil transmission stations helps to detect and track the targets at far distance. By a development and research plan which continued for many years, the Center’s specialists developed and produced many (silent) systems and the specialists of Saudi Armed Forces conducted a number of trials and tests for the System. The manufacturing rights of the System are being transferred to a national industrial company which is qualified to produce the system with the quantities, specifications, and requirements of the Armed Forces.
It is a tactical radar system. In cooperation with a technical partner, this system was carried and Saudized. The ground sensing system (Shafaq) detects air targets (at low heights) as well as marine and ground targets. These radars use low-power electromagnetic signals with FMCW Technique which can be hardly discovered or hindered at a far distance. These radars are highly sensitive; it can detect and track targets with small radar section. They are also light and can be easily carried and used on four-wheel drive cars. The System was tested under operational circumstances in cooperation with specialists of Saudi Armed Forces. This System performs many operational and technical functions, notably:
The following actions were made within 2019:
Homeland Shield System
It is a national system which is being developed by the Center for the purpose of building a national effective capability to overcome the threat of remote control drones and boats whatever their type. This System is customizable as per the threat and can perform the following functions:
