The development of radar signal simulator in specific environment can effectively accelerate the debugging process of radar system and reduce the consumption of human, material, and financial resources. This study analyses the mathematical model of the IF radar signal in aerial distributed semi-active radar system and deduces the parameters of radar signals based on direct digital synthesiser (DDS) technology. After solving the problem of multi-channel synchronisation, delay precision control, and envelope delay compensation, an IF radar signal simulator system was designed and implemented, which can generate three direct-path-wave signals and three echo signals.
