Product Category : Radar And Assembly
Bharat Electronics provides Medium Range Air and Surface Surveillance Radar or F-Band Radar System, PFN 513. The product Medium Range Air and Surface Surveillance is designed for use onboard large and medium naval ships or in shore establishments. Medium Range Air and Surface Surveillance provides medium range air warning, surface warning and target indication to fire control equipment. High PRF in MTD mode facilitates sea skimmer detection. Medium Range Air and Surface Surveillance is provided with an Antenna with Stabilised platform. Medium Range Air and Surface Surveillance consists of a Platform control cabinet, Hydraulic power unit, Transmitter unit, Low level signal generation, Receiver and Signal processing unit. Medium Range Air and Surface Surveillance is also facilitated with Monitor display, Waveguide drier, Operator control console and Radar Processor unit. The salient features of the Medium Range Air and Surface Surveillance:
High sensitivity multichannel coherent receiver with adaptive STC
Raster scan colour display with TWS and TD facilities
Synthesizer based coherent transmitter with random agility
Chirp pulse compression with high average power
Moving target indication with digital delay line canceller
Stabilised two speed double horn light weight antenna
High PRF mode with MTD processing
Built-in Test Equipment for easy repair and maintenance
