Features:
- all solid state design;
- full coherence is implemented, owing to which radar parameters are significantly improved;
- wide range of narrow- and broadband probing signals enabling radar adaptation to various combat conditions;
- digital signal processing, including matched filtration, clutter and active jamming suppression, target detection and coordinate measuring, target tracking and data distribution to consumers;
- practically approved reliable software, user-friendly interface;
- only COTS components are used from renowned suppliers, this coupled with quality system approval guarantees the high level of reliability.
Advantages:
- large number of probing signals, ability to choose the best depending on air situation, jamming and combat conditions;
- Parameters of probing signal - working frequency, modulation type, waveform - reconfigurable;
- reconfiguration of signal parameters can be carried out via program or randomly (reconfiguration of probing signal parameters does not affect the quality of clutter suppression);
- increase of signal to noise ratio due to matched filtration of received signals, increase of detection range and accuracy;
- significant (up to 100dB) increase of dynamic range resulting in high jamming immunity and suppression of local targets and weather formations;
- efficient algorithms of clutter suppression with wind speed compensation;
Dejamming capabilities
A range of hardware and software solutions are implemented in the radar P-190U enabling suppression of the following kinds of jamming:
• nonsynchronous and chaotic pulse noise;
• response pulse noise;
• active noise jamming.
