The anti-jamming capability of phase coded waveform with limited side-lobe level in correlation function

Pulse compression is a desirable approach to design pulses in jammed environment. It is important to have a phase coder sequence which has limited side-lobe level in correlation function, in phase coded pulse compression. This paper is discussing about the anti-jamming property of phase coded waveform which is coded with a sequence which has correlation function with limited side-lobe level. This sequence is constructed with minimizing the Integrated Side-lobe Level (ISL). After constructing this sequence it is used to modulate the pulse in jammed environments and its capability is measured in two different jamming scenarios called deceptive jammer and barrage jammer. It is observed that in barrage jammer scenario this phase coded waveform can resist very powerfully and in deceptive jammer scenario it can, too. In later scenario the anti-jamming capability of the waveform depends on the length of phase coder sequence.
