From the perspective of radar detection system configuration, the 054B frigate is different from the 054A, and this battleship is very likely to be equipped with a radar with a four-sided array and dual-band structure. As we all know, radar functions through wavelength bands, in which radars with long-range exploration capabilities have longer wavelengths, while radars that meet the needs of fire control operations have higher wavelengths. Based on the different nature and composition, the combat side needs to choose different styles of radar devices according to the operational environment and other factors.
In the deep phased array combat environment, short-range engagement and long-range detection and other processing methods can be adopted. Among them, in the state of short-range engagement, the phased array radar can concentrate on dealing with a large number of anti-ship missiles from the opponent by performing the role of gazing and other functions. During this time, they are able to track and guide multiple incoming missiles. It is reported that high-frequency radar can generally be installed at the top of the mast, mainly based on the small antenna array, and the task of long-range search is completed by a large antenna, after all, this does not require an excessively high data rate.
If long-range detection methods are adopted, in order to accurately handle short-range engagements, it is necessary to have comprehensive and effective control of the long-range air situation. In order to search and track targets at long ranges, phased arrays of medium and low frequencies are installed to complete saturation attacks. It is worth noting that if you want to maintain a strong firepower under such means, it is better to install several more fire control radars.
In addition to the above two means, phased array radars can be installed and used in all of them, so as to achieve dual-band radar control, so as to maximize the most powerful attack potential. It is understood that the 054A is equipped with a back-to-back 382 radar, which can be easily transformed into an S-band double-sided array style. In this regard, China continues to extend and develop on this basis, and the X-band double-sided array with increased data rate can meet the needs of frigates.
The Haihongqi-16 guidance mode is active radar guidance, and the fire control radar does not have to be continuously illuminated. When dealing with long-range targets, it is necessary to use an S-band search radar with general data rate characteristics. During this period, through the guidance of X-band data, we can continue to maintain tracking operations without showing the characteristics of real blind spots. Of course, we can also adjust the rotation speed to lock on to high-threat targets or track other threat targets. When the high-threat target disappears, it returns to its normal state.
In conclusion, maintaining a high threat status is not something that corvettes often need to deal with, otherwise it would be better to install a four-sided array. From the point of view of external structure, it is a certain fact that our country has indeed achieved positive results in dealing with low-cost construction. In our opinion, the 054B is indeed the world's first frigate equipped with a dual-band radar.
