Current article gives overview about use of software defined radio concept in the field of radar technology. Software defined radio is shortly introduced. Mainly is described buildup and work principles of software radar device and as a next level network of Software Radars. Rapid development in signal processing technology allows totally new approach to data acquisition systems. Performance of radar devices no longer depend only on analogue or even digital part of their structure. Reprogrammable and powerful data processing devices together with fast and reliable networks opens a huge number of totally new possibilities on a field of radar technology. Experimental radar device, built for testing Software Radar theory is also briefly introduced. Ill. 4, tabl. 1, bibl. 7 (in English; summaries in English, Russian and Lithuanian).
