The material for the Type 346 radar comes from a guy who once worked on the project and has since moved to Canada long ago. What he wrote was after he immigrated and also documented the institute rivalries, and even things the other rival institutes would do to get on top by throwing obstacles at your work. These were the things that happened back in the early to late '90s so we don't exactly know what is the work atmosphere much later. If its propaganda, you won't be exposing the dirt and rivalries within your defense industry complex.
For example:
按理说,4单元T/R组件研制成功,舰载相控阵雷达的研制经费就应该下拨了。但事实并非如此。我们接到通知,舰载相控阵S波段雷达方案要被再次评审,并要与航天部二院23所的C波段雷达方案进行再次比较。我当时觉得很奇怪,已经定下来的事,怎么还要再审?后来才被告知, 当我们潜心于T/R组件,天线小面阵等关键技术突破时,23所整理了有关S波段雷达的一串问题,经航天部这条线,捅到总理李鹏那里(李鹏是亲航天部的)。于是,14所被通知在5月底接受“10院士”评审团的再次评审。
It stands to reason that if the 4-unit T/R component is successfully developed, the development funds for the shipborne phased array radar should be allocated. but it is not the truth. We have been notified that the shipborne phased array S-band radar scheme will be reviewed again and compared with the C-band radar scheme of the 23rd Institute of the Second Academy of the Ministry of Space. At the time, I thought it was very strange. Why should I retrial something that has already been decided? It was only later that I was told that when we were concentrating on breakthroughs in key technologies such as T/R components and small area antenna arrays, the 23rd Institute sorted out a series of questions about S-band radar, and went through the line of the Ministry of Aerospace to get to Premier Li Peng ( Li Peng is pro-Space Department). As a result, 14 institutes were notified to accept the re-evaluation of the "10 Academicians" jury at the end of May.

His description of a 4 unit T/R component easily fits the description of a QTRM or Quad Transmit Receive Module, which is common with AESA radars. Not something the average Joe can make.

So is knowing that Institute 23 has a C-band radar scheme. Institute 23 is the institute responsible for the HQ-9 system and made the HT-233 radar that serves the HQ-9. Guess what, this radar works on the C-band, similar to the MPQ-53 on the Patriot.

Institute 23 is competing with Institute 14 for the naval radar and is proposing a C-band radar arrangement. However, the C-band isn't capable of reaching the ranges the PLAN wants, versus what Institute 14 is proposing with its S-band radar arrangement. No average joe knows who these institutes are, but if you like to know more, Institute 14 is NRIET which is based, as the N says, in Nanjing. NRIET is responsible for the radars on the J-10, J-11, J-20 and so on, hence why these radars are called Type 1473, Type 1475, the "14" obviously points to Institute 14.
The thing to consider about this link is that the writer might have a chip in his shoulder from his workings in the Chinese military industrial complex. And of course, losing techs like him to immigrate to other countries is a loss for the Chinese defense establishment.
