DR-151
The DR-151 is a low-flying reconnaissance radar in the D-tape km with a range of 45th So far, many modernizations such as digital signal processing, which has been proven to improve interference immunity (EPM), as well as improvements in the mechanical construction have been carried out. The entire system is built on a 10 ton truck and equipped with an 18 m high extendable mast. The new transmitter received technical components such as 90 selectable channels and works with the pulse compression method with digital pulse stretching and pulse compression using SAW filters . The digital signal processing works with a dynamic 12 bitbroad A / D conversion with Fourier analysis for automatic target acquisition and can thus distinguish rotary wing aircraft from aircraft with rigid wings.
