At present,millimeter-wave radar seekers often use stepped frequency signals to obtain high-resolution range profile.The stepped frequency signals feature large synthetic bandwidth,flexible waveform design,and strong anti-jamming capabilities.Therefore,it is of great significance to simulate the echoes of the stepped frequen-cy radar and to study matching jamming techniques.This paper analyzes and simulates the jamming effect of the conventional noise suppression and storage forward jamming techniques in self-defense countermeasures scenarios,with the hysteresis of the jamming systems in actual countermeasures being taken into consideration.It can provide some reference for the design and use of related jamming equipment.
