LPI Performance Analysis of Coded Frequency-hopping Signal
Chaoshu Jiang · Modern Radar · 2011
In this paper,combined with the development of the technology of interception receiver,a new concept which is based on the recent low probability of exploitation is elaborated,and the interception exploiting factor is defined.By analyzing two general interception processing methods,i.e.,dechirping and cyclic spectral analysis,the code frequency-hopping signal and the other four LPI radar signals are compared on the interception processing gains and the interception exploiting factors by simulation.The simulation results show that,because of its large time-bandwidth product and randomicity,the code frequency-hopping signal has good anti-interception performance against the two methods.
