The new generation of radar has to be equipped with a high performance exciters and receivers to cope with the
threat in an Electronic Warfare scenario. The threat in a complex environment with interfering signals requires a reliable signal generation with proper frequency agility and efficient gain controls in receiver units. This is quite cumbersome to achieve in analog domain. Due to digital technology advancements, it is possible to have efficient and high performance Analog-to-Digital converters (ADC),processors, high-density memories and efficient algorithms to realize highly reliable, flexible and upgradeable exciters and receivers.
