Radar P-190U

The 2D Surveillance Radar P-19МА is a new product from "UKROBORONSERVICE" SC. This product implements all of the modern design methods combined with the longstanding experience of the company.

Automated workstations:
- Tanker workstation with a remote control (left);
- Operator workstation (right)



Among its main features are:

- full coherence is implemented, due to the significant improvements in radar performance;

- a 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 developed by Aerotechnica with a user-friendly interface;

- only COTS components are used from renowned suppliers - this coupled with quality system approval guarantees the high level of reliability.

Radar design
The design of the radar can be changed in accordance with customer requirements.
The radar equipment can be placed on ZIL, KrAZ, KAMAZ vehicle chassis (and similar) or in a fixed-position shelter.
As an option, this equipment can be installed in a modified hardware compartment of the P-19 radar. A partition is inserted in this configuration in order to separate hardware and operating personnel. The advantage of this option is that it lowers the price of the radar.

All the equipment is installed in one compartment. Hardware is mounted on the walls on specially designed frames providing easy access to all composite elements and easy maintenance.

There are operator working positions and remote working position with seats for operating personnel.
Among its main features are:

- full coherence is implemented, due to the significant improvements in radar performance;
- a 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 developed with a user-friendly interface;
- only COTS components are used from renowned suppliers - this coupled with quality system approval guarantees the high level of reliability.

Among the essential features of the equipment developed are full automation, elimination of possibilities for human operator error from combat activity, a user-friendly interface, highly productive signal processing system - all of which lead to significant improvement of radar characteristics.
Advantages of P-19МА:


- large number of probing signals, ability to choose the best depending on the air situation, jamming and combat conditions. For instance, narrow band for near field (good detection against clutter background), broadband for long range (large detection range, especially for smaller size targets);
- parameters of probing signal - working frequency, modulation type, waveform - are all reconfigurable;
- reconfiguration of signal parameters can be carried out via program or randomly (plus, 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;

Dejamming capabilities

A range of hardware and software solutions are implemented in the radar P-19МА enabling suppression of the following kinds of jamming:
- nonsynchronous and chaotic pulse noise;
- response pulse noise;
- active noise jamming.
Suppression of pulse noise is implemented in software and enables full suppression of pulse noise.

For suppression of active noise jamming including interfering from TV centres, radios and other sources the following steps are implemented:
- automatic monitoring of active noise conditions and automatic adaptive working frequency hopping 0.4 MHz discreet;
- high dynamic range of signal processing system (of the receiver and digital signal processing unit) - 105dB;
- extra expansion of dynamic range (by 30 dB) through automatic gain control;
- 4-channel dejammer of active jamming is offered as an option, providing jamming suppression of 32 dB (at SNR of 40 dB).
