NOLR－6；电扫超外差接收机，极类似于美国的WI。R－8．于70年代初问世，频率覆盖至18GHZ。该接收机用一对旋转的测向天线覆盖雷达频段，再加上装在前中桅平台上的环形偶极子测向天线覆盖甚／特高频波段。相应的潜艇系统是对，R－3／5。OI。R－9显然是相应的党开导弹告警系统．
NOLR-6; E-scan superheterodyne receiver, very similar to the United States WI. R-8. In the early 70s came out, the frequency coverage to 18GHZ. The receiver covers the radar band with a pair of rotating DF antennas plus a ring dipole DF antenna mounted on the front-mid-mast platform for VHF bands. The corresponding submarine system is right, R-3/5. OI. R-9 is clearly the corresponding party open missile warning system.
