Ground-based mobile UHF low, medium and high altitude surveillance radar P-190U is offered as the modernized follow-on to its prototype, the analogue P-19.P-190U radar features: maximum use of COTS components; stable, fail-soft, modular solid-state transmitter; built-in test equipment; no special adjustments required during operation; largely simplified maintenance; engineered for minimum cost of ownership.As a result of modernization the radar’s detection performance is efficiently improved. Modernized radar features automatic tracking capability as well as data receiving from other radar sensors. Data can be exchanged over a variety of communication channels in approved format. Depth of modernization:The radar’s equipment cabin is fully modernized. Frequency range is preserved at 825-890 MHZ, however the number of working frequencies is increased from 3 to 160, the capability of instantaneous electronic frequency agility is added. Radar transmitter and receiver feature solid-state components only. The transmitter has a modular design and provides ‘soft-failure’ redundancy: failure of individual module leads to partial performance degradation.
