P-18-2 Radar Upgrade (Version 2

Radar Upgrade (Version 2)

Purpose

The P-18 radar modernisation programme is proposed to replace vacuum-tube components with solid-state technology and improve the radar performance. Composition

Equipment to be modernised includes: • active jamming suppression equipment; • digital passive interference suppression equipment; • transmitter control display and automatic frequency control amplifier; • automaticradar data reading and recording equipment; • receiver and coherent local oscillator.

Target detection range (POD=0.8),km:

RCS = 2.6 sq.m, activenoise directed-barrage jamming spectral density = 200 W/MHzgenerated by four jammers from 200-km range and 10,000-m altitude: at 3,000 m 84
