Type AMR-1 Chinese Radar
This is a sample record of the Type AMR-1 Active Missile Radar, from our major dynamic report about radar systems deployed in China. The Chinese Radar Report is available now in .pdf format or CDROM. At over 600 pages it is the only work of its type and deals with all aspects of radar and their development in China over the last 30 years.
The following AMR-1 sample text and images are taken from the Report and give an example of its format and content.

Being a very modern system it may also have a passive home-on-jamming (HOJ) facility and be able to discriminate between chaff, active decoys and real targets.
Significantly, perhaps, it is reported that the AMR-1 is intended primarily for the export market.
Little is known yet about this new (2007) system except that the AMR-1 is reported to be an advanced next-generation, medium-range, terminal guidance, air-to-air, active radar missile seeker that has been developed indigenously by CLETRI, initially at least for the PL-11B AAM . The PL-11 and PL-11A relied upon semi-active seekers based on the Italian Aspide missile design whereas the PL-11B is the first indigenous fire-and forget medium-range air-to-air missile (MRAAM) with an autonomous active seeker.
However, the latest indications are that the AMR-1 may also be destined for the SD-10 (PL-12) AAM.
Based on available evidence, AMR-1 appears to be a sophisticated miniature pulse Doppler radar with a flat plate slotted waveguide array antenna, capable of target search, acquisition, tracking and homing in all weather conditions, and in a complex electromagnetic interference (EMI) environment, but detailed parameters have yet to be announced.
Measurements taken from available pictures, against the missile’s reported diameter of 208mm, tends to suggest that this seeker functions in J-Band probably in the range 15.4 ~ 17.7 GHz). However, it has been suggested that the AMR-1 may contain design influences from the Russian R-77 AA-12 Adder AAM seeker, which is the AGAT designed and developed 9B-1348E, which functions in I-band, although there are also reports that an R-77 variant contains the J-Band 9B-1103 seeker.
The types of scan used are not yet known, but as a medium range AAM, it might use a sector scan to search for and acquire targets at extreme range whereas a raster pattern might be used to acquire shorter range targets over a larger vertical field of view, especially if the launch platform is manoeuvring. It is suspected that some form of target prompting will be used immediately prior to missile launch and that may come directly from the launch platform’s own radar.
