Radiolocation means radio search and targeting of objects in space using electronic waves. Radio technical equipment used for this purpose is called radars. The English name RADAR is an abbreviation of these words: RAdio Detection And Ranging. Radar performs two basic activities. Detects an object and measures its motion parameters. Other activities can also be object identification, etc. Object detection issues include detecting the reflected signal against background noise and interference in the entire range of signal parameters (signal delay, frequency), as well as space overview or space search determined by the limits.

In 1935, Adolf Hitler succeeded in concluding a major maritime agreement with Great Britain. Under the agreement, Germany was able to build 35% of the tonnage of British battleships, aircraft carriers, cruisers and destroyers. The construction of submarines was also allowed. In the first phase, 45% of the British tonnage was allowed and for the next stage there was even talk of compliance. This treaty, in its consequences, annulled the conclusions of the Versailles arrangements. After the conclusion of this contract, the construction of the so-called pocket battleships was abandoned and the construction of much larger and, according to the original plan, much better armed.
