   Our enterprise has many years experience in modernizing radars for various purposes, like military, weather, air-traffic control, civil aviation radars which were manufactured earlier.

   Obsolete vacuum travelling wave tubes (TWTs) which are not manufactured are replaced by microwave modules (of MSHB, ELU-type) allowing to avoid many generally known disadvantages of TWTs:

TWT MSHB, ELU modules
  1. Limited service life – up to 500…1500 hr;
  2. High noise level which increases during operation;
  3. Necessity of adjustments when mounting and during operation;
  4. Deterioration of performance when exposed to magnetic fields (also in case of a close arrangement of some TWTs);
  5. High energy consumption;
  6. High price
  1. Guaranteed service life min. 10000 hr;
  2. Substantially lower and stable noise level;
  3. No need of adjustment;
  4. Resistance to exposure to magnetic fields;
  5. Modules are connected to one stabilized power supply + 7(11,5 )…28V, 40…120 mA reducing power consumption by several fold;
  6. Low cost

   Such modernization may be carried out both by specialists of our enterprise and by operating personnel directly in radar position, practically without removing radars from operation. There is no need of making changes in radars because all mounting dimensions of microwave modules correspond to those of replaced units and TWTs.

   Owing to modernization, radar receiver sensitivity increases by 2…7 dB (depending on radar type and condition and replaced TWT) and in some cases even more resulting in detection and tracking range increase of air and water targets, particularly those with small specular cross-section.

   Such modernization of the radars of air-defense missile systems substantially increases detection and tracking range in automatic mode, improves picture sharpness on the radar scope, gives more accurate position of observed objects, finally raising fighting efficiency of the system as a whole.

   Besides TWT replacement by solid-state microwave modules, we modernize other units of radar receiving sections made of obsolete components ( glass and metal-ceramic tubes, obsolete diodes of waveguide mixers and others ) which are critical from the point of view of performance, service life and reliability.

   The results of such modernization of various radars confirm its technical and economic expediency. It is the cheapest way of prolonging service life with simultaneous substantial improvement of main tactical and technical characteristics of the radar as a whole.

   Taking into account many years experience, our specialists are ready to consider proposals for modernization of any existing radars as well as for development and deliveries of microwave modules for new generation radars being developed, including those with phased array and active phased array.
