PIT - Radars and Command and Control Systems

Established in 1934, the Telecommunications Research Institute, or Przemyslowy Instytut Telekomunikacji (PIT), is Poland's largest national defence R&D centre, with three operational locations. For over fifty years PIT has developed military radar systems, command and control systems and electronic warfare equipment.

PIT's equipment is used by all three military services, and some solutions are also ideal for coastguard and homeland security services. PIT activities include supporting the requirement-definition programme of products, and their development, design, small-scale manufacturing and maintenance. PIT is a national focal point for the NATO AGS programme.

TRD-1235 LONG-RANGE SURVEILLANCE RADAR

The TRD-1235 3-D L-band long-range surveillance radar is used as an effective source of radar information for air-defence command and control systems. These surveillance radars have been successfully incorporated into national air-defence systems. The output of primary radar information, associated IFF data and auxiliary data is in ASTERIX (EUROCONTROL) and / or a user-defined format.

TRD-1235 3-D L-band long-range surveillance radars were designed for unattended operation with remote control/monitoring. They consist of a passive phased array antenna unit of 10m span and 6rpm rotation, a TWT / CFA fully coherent transmitter and a signal processing and displaying unit. A remote (up to 1km) display workstation is available. The TRD-1235 surveillance radar is specially designed for operation on top of a fixed-site tower.

The standard version of the TRD-1235 detects the airborne targets in 3-D at an instrumented range of up to 470km and at heights up to 30,000m. The long-range surveillance radar is able to detect and automatically track up to 250 targets. Effective clutter and jamming immunity is achieved using adaptive signal processing and numerous other techniques.

TRS-19 MEDIUM-RANGE SURVEILLANCE RADAR

The highly-mobile TRD-19 3D S-band medium-range surveillance radar is capable of providing accurate 3-D data for airborne targets in a search volume of 180km in range and 30,000km in height. Up to 120 targets can be tracked simultaneously.

The air targets are located using the stacked-beams monopulse technique for estimation of elevation and the mechanical scanning in the azimuth plane.

The radar data, including the IFF data, is provided to an internal or external operator workstation. The output of primary radar information, associated IFF data and auxiliary data is in ASTERIX (EUROCONTROL) and / or a user-defined format.

The surveillance radar is applied as a gap filler, detects low-level targets excellently, and is equipped with an inertial orientation of antennas and a GPS geographical location system. The TRD-19 3D S-band surveillance radar is deployable in 20 minutes by a crew of three.

SECTOR-AIR OPERATIONS CENTRE

PIT has developed the Sector-air Operations Centre (SOC) to perform complex command and control functions of collecting the air picture data and, on the other side, of supporting the decisions on use of the combat means. The SOC consists of two components: a Recognized Air Picture (RAP) Production Centre (RPC), and an Air-Control Centre (ACC).

The RPC is intended to produce and to disseminate the RAP information within the national air-defence system and to other users. The RAP production process consists of gathering the air targets' plots and tracks in the area of RPC operational-responsibility, to create a Correlated Air Picture (CAP).

The data is collected from the radar sources directly and via PIT-developed radar reporting posts. The next step is identification of air tracks, which is based on the data from SSR and IFF, civilian and military flight-plans, the data from adjacent SOCs and the information received from the ESM systems. Identification information is assigned to tracks to create the RAP.

The Air Control Centre (ACC) provides automation of the decision-making process for management, command and control of subordinate combat means such as PIT-developed SAM operation centres, fighters' interception control-posts and electronic warfare.

The ACC and RPC are distributed computer systems with open and scalable hardware and software architecture. Radar-data gathering, RAP distribution, and command and control data-exchange have network-centric capabilities. The SOC system provides interoperability with other systems at the required level.
