In the domain of electronic warfare, jamming is an eavesdropping application. Spread Spectrum systems are RF communications systems, in which spread the information bearing digital signal across a broad bandwidth by injecting a higher-frequency signal. Spreading the energy of a bounded energy data signal across a very wide bandwidth causes the energy present at any particular frequency or small frequency band to be insignificant, which makes it transparent, but also vulnerable. In the

In the environment where blasts are occurring that can be modeled as thermal noise at that frequency, DSS's energy spreading can be affected because of its sensitivity in the environmental reflections. In this context, this paper presents an innovative approach about the effects of fire blast effects in the neighboring DSS communications. This work includes a simulation of the jamming effects and compares the effect of jamming technique on the performance of a DSS signal with those available in the literature. The results of this simulation will be used to extract the maximum sensitivity of receivers and the maximum error rate by which the DSS communications can be implemented.
