SNR improvement in electronic support measures systems via pulse integration

Abstract

In ESM (Electronic Support Measures) systems, detection of intentional or unintentional modulation on pulses requires high SNR. By integrating the collected pulses emitted from the radar, SNR can be increased. For utilizing pulse integration, all the pulses should be aligned in time very accurately. In this work, we propose a new method, which estimates the time shifts between the pulses with very high accuracy and resolution. Experiments on both synthetic and real data sets show that proposed method aligns the radar pulses very successfully.
