Talk:Type 364 radar

Untitled

In the wake of the EP-3E Hainan incident, 'International Report' has received insight into current mainland Chinese radar technology in the form of details of the Type 2405 shipborne surveillance radar. Developed by the Nanjing Marine Radar Institute (NMRI), the Type 2405 sensor is described as being a C-band (4 to 8 GHz) multifunction equipment that is designed for shipboard air and surface surveillance, target indication and anti-shipping missile defence. The radar is equipped with a [cosecant.sup.2] lightweight stabilised antenna that provides 500 coverage and a sidelobe value of-30 dB. Stabilisation is in both pitch and roll, and the equipment makes use of a 'wideband, high power, transistor-travelling wave tube' transmitter chain that incorporates solid-state modulators and a wideband linear receiver. The Type 2405 is further noted as making use of stable frequency synthesis, frequency agility, digital moving target indication, constant false alarm rate, sidelobe suppression and variable polarisation (ho rizontal and vertical). Data display is by means of a colour raster terminal and the sensor's antenna assembly incorporates an integral identification friend or foe array. At the -3 dB point, Type 2405 has an azimuth beamwidth of [1.5.sup.[degrees]] and the sensor is described as having azimuth and range accuracy values of [0.3.sup.[degrees]] RMS and 50 m RMS, respectively. The type's resolution values are given as being 20 in azimuth and 150 m in range and its antenna scans at the rate of either 15 or 30 rpm, depending operator selection. NMRI further notes that the Type 2405's antenna assembly (including its stabilisation platform) weighs less than 520 kg and that its free space coverage extends to an altitude and range of plus 9 km and plus 96 kin, respectively.

Same radar but from Nanjing?
