LP-23

The LP-23 (“Long Porter” with 23 cm wavelength) is a D-Band long-range surveillance radar for en-route air traffic management. LP-23M is a conventional magnetron radar with a range exceeding 220 nautical miles against a two-squaremeter target. A klystron-powered derivative, the LP-23K, was also available.

The more modern LP-23SST (solid state transmitter) fitted with the RSM 970 S monopulse secondary radar is a widely used en-route radar. It uses frequency diversity and an LFM intrapulse modulated long range pulse. The pulse compression ratio is selectable between 66:1 and 200:1. The successor of this variant is the TRAC 2000N then.
