Optimal jamming waveforms based on spot jamming to TDRSS;

Based on the operation characteristics of conical scan angle tracking system, the paper presents the spot jamming method against conical scan radar, discusses the instances when conical scan frequency error is zero and the error is general, and analyzes the jamming effect.

Simulation results on the spot jamming efficiency of floating-type jamming equipment provide a reference for establishing the countermeasure against TACAN system.

Research of GPS receiver acquisition performance under narrowband jamming;

Finally suppression of the narrowband jamming in the subspace after it is projected is discussed too.

Models of narrowband jamming are analyzed and simulated in this paper.

Novel suppression method for narrow-band interference in GPS receiver;
