Shuimen Air Force Base, Xiapu, Fujian. (PLAAF)

An overview to the area:

      Shuimen AFB Passive radar network
      Passive radar network including 4 passive radar sites and 1 control site.
      Air surveillance radar site x1 (PLAAF)
      Air surveillance radar site x1 (Unidentified)
      HQ-9 SAM site x1, including a HT-233 fire control radar.
      And a site with probably 3 microwave antennas (2 with antenna radomes), could be an electronic support (ES) site.

The direction of the red line is pointing to the Diaoyutai/Diaoyu/Senkaku Islands in the East China Sea. It has the same pointing direction as the airport's runway.

Maybe this aiprort is dedicated for the Diaoyu Islands, as they normally don't put such expensive Sukhoi fighter close to the coast line of Taiwan Strait, this AFB seems to be the only exception.

A close-up view to control site, radar site #1 and communication node of the passive radar network. Site on the buttom left is assumed ES site. (Better guess? Welcome! )

The trip (red line) to Diaoyutai/Diaoyu/Sankaku islands will be very boring, if you take off from west side of the runway.

Passive radar site #2. Seems to have a underground facility below.

The radar is installed in a shelter of a vehicle, and there's a telescipic mast for mounting the radar and data link antennas. All passive radar vehicles should have the same configuration except 3 data link antennas/ transmission systems (Comm node) are required in site #1 in order to obtain the received target data from the 3 sites deployed in the front.
