Researches on radar technology

In Electronic Systems Research Center (ESRC), various researches have been conducted to realize defense radars with excellent functions and performance. This presentation introduces some of those radar research programs. Especially, the research concerning active phased array antenna started in an early stage of the 1970s. Successive various basic research programs have been conducted and finally led to successful development of first airborne active phased array antenna radar, J/APG-1, in Japan. The multifunction RF (Radio Frequency) sensor, the passive radar, the wall through radar and the space time adaptive processing are under research at present.
