DR-151

The DR-151 is a mobile low-level surveillance D-Band (1200 to 1400 MHz) radar with a range of 45 km. Other improvements have been made in features such as signal processing, Electronic Protective Measures (EPM) proofing and mechanical design. The system is mounted on one 10-tonne truck and is equipped with an 18 m extensible antenna mast. The new transmitter has technical features such as 90 selectable channels, pulse expansion by digital pulse expander, and pulse compression by SAW- filters. The signal processing includes features such as 12-bits dynamic range, discrete Fourier transformation, target extraction by amplitude quotient procedure, and helicopter/fixed-wing aircraft distinction.

An older version of this radar was already retired in 1990 in the German Air Force as the TMR MPDR 30/1 “low-altitude reporting radar”. The DR-151 in the modernized version described here is still in use in the Pakistan Air Force, but uses the base and the antenna of the TMR which was decommissioned in the German Armed Forces.
