TRD-1211
The TRD-1211 is a D-band working 3D large-capacity radar from the Polish manufacturer Przemyslowy Instytut Telekomunikacji.
The TRD − 1211 consists of three main assemblies and a power supply unit. It can be transported with a few trucks equipped for the transport of containers according to the ISO standard. The antenna is a phased array antenna that is divided into two groups.
The (upper) transmitting antenna forms a Cosecans² transmission diagram and the (lower) receiving antenna forms eight narrow receiving diagrams, staggered in height. The diagram is pivoted horizontally by mechanical rotation of the entire antenna system and vertically by electronic beam shaping. The reception path is divided into eight channels that work according to the monopulse principle. The transmission pulse is 20 µs long and linearly frequency modulated. The echo signal is compressed to 0.4 µs using the pulse compression method .
The radar data processor of the TRD − 1211 can detect and automatically accompany up to 120 target objects up to a distance of 350 km and up to 40 km altitude.
The TRD − 1211 was developed as a radar sensor for networked air defense systems. It provides information about the air situation that can be transmitted to the control centers via digital radio or wire connections with medium data throughput density.
