China unveils new 610B anti-stealth aircraft radar.

| 2023

During the 2023 Changchun Air Show, the Chinese anti-stealth aircraft radar that was previously showcased in the 2019 National Day military parade received an official designation as the Type 610B radar. Despite being displayed before, the specific model name of the radar had not been disclosed until now.

According to a tweet by Jesus Roman, the radar unit showcased at the event exhibited a variety of significant details on its dashboard plate. Also known as Type 610B on Chinese social media, the radar unit featured at the event bore the identification LCG610. Its serial number was 1, and it was referred to as the "Antenna Car." With dimensions of 12000×2500×3520mm and a weight of 49 tons, the radar unit was manufactured in March 2008 at the 14th Research Institute of CETC. It carried the factory number 5220708016 and belonged to batch number 4600001. Notably, the radar unit appeared to be mounted on an 8x8 NORINCO-Beiben Heavy Duty Truck 4038A.

The 610B radar represents a novel vehicle-mounted phased array warning radar developed by the 14th Institute of China Electronics Technology (CLP 14). It belongs to the fourth generation of domestic air defense and anti-missile early warning radar and plays a crucial role within the Chinese air defense network.

Its primary function is long-range early warning, specially designed to detect combat aircraft, including stealth aircraft. Additionally, it possesses the capability to identify tactical ballistic missiles and nearby space targets, making it an invaluable asset for air defense operations.

The radar's design stands out with its distinctive cylindrical transmitter antenna, setting it apart from other Chinese radar models. Interestingly, its appearance bears a resemblance to the foreign trade version of the SLC-7 intelligence radar, exhibited at the 2016 Zhuhai Air Show.

Operating in the L-band, the 610B radar is estimated to have approximately 7616 array elements and a large aperture of around 48 to 62 square meters, providing a substantial advantage in terms of detection and tracking capabilities.

In comparison to the AN/SPY1D radar used in the US "Aegis" system, the 610B radar exhibits superior performance due to its narrow beamwidth, resulting in higher precision and accuracy. The potential utilization of GaN (gallium nitride) technology may further enhance its output power and extend the detection range. Moreover, the radar's transmitter antenna incorporates specific features intended for enemy identification, enhancing its situational awareness and threat analysis capabilities.

The 610B radar is part of the Type 610 radar family, which includes other radar systems developed by the 14th Institute of China Electronics Technology Group Corporation, such as the 610A radar.

The 610A radar boasts robust capabilities for countering stealth, jamming, and target classification and recognition. However, information about the 610 Radar remains scarce, with only two official account articles from the 38 Institutes providing a brief introduction. It is known that the 610 radar operates in the S-band as a digital array radar and possesses exceptional anti-obscurity capabilities. The official account article suggests that the R&D team's aim is to push the limits of technology rather than merely competing with others. Roughly estimated, the frontal area of the 610 radar is approximately 4.6 meters, corresponding to around 9600 transmit-receive modules (TRs).

The Type 610 radar serves as the backbone of the Chinese fourth-generation long-range early warnings for air targets, including stealth aircraft, and is also effective in detecting tactical ballistic missiles and adjacent space targets. In contrast, the Type 609 radar plays a crucial supporting role to the Type 610 radar.

The Type 609 radar stands out for its multifunctionality, high power, maneuverability, and adaptability to complex electromagnetic environments. On the other hand, the Type 610 radar features an advanced technical system, diverse detection modes, anti-stealth and anti-jamming capabilities, and precise target classification and identification capabilities.

Stealth technology and the proliferation of stealth fighters have posed significant challenges to existing global air defense systems. Consequently, developing anti-stealth capabilities has become a common goal for military powers worldwide. Modern ground air defense intelligence radar systems need to seamlessly integrate air defense and anti-missile capabilities, have digital technology integration, incorporate adaptive and intelligent technology, detect and identify air and space targets using broadband high-resolution radars, and possess robust electronic counter-countermeasures (ECCM) capabilities. Additionally, advanced structure, process design, and manufacturing technology should lead to miniaturization, flexibility, and lean design to enhance overall radar efficiency and performance. By adopting these development characteristics and trends, nations aim to bolster their defense capabilities in the face of evolving and complex threats.
