The Linear Frequency Modulation (LFM) waveform represents the prevailing form of pulse compression utilized to enhance signal-to-noise ratio (SNR) and offer effective range resolution for pulsed radar systems. It is acknowledged that generating LFM pulses exhibiting high energy levels within brief time durations poses a notable challenge for pulsed radar systems. The present study examines the performance of the pseudo-random stepped-frequency LFM (SF-LFM) radar pulse train compressed using Dispersive Delay Lines (DDL) in the presence of noise. The findings indicated that the novel method of waveform synthesis, achieved through the fusion of SF-LFM waveform with binary pseudo-random sequences, presents benefits such as noise immunity, cost-effectiveness, ease of implementation, and reduced power consumption.

摘要

The Linear Frequency Modulation (LFM) waveform represents the prevailing form of pulse compression utilized to enhance signal-to-noise ratio (SNR) and offer effective range resolution for pulsed radar systems. It is acknowledged that generating LFM pulses exhibiting high energy levels within brief time durations poses a notable challenge for pulsed radar systems. The present study examines the performance of the pseudo-random stepped-frequency LFM (SF-LFM) radar pulse train compressed using Dispersive Delay Lines (DDL) in the presence of noise. The findings indicated that the novel method of waveform synthesis, achieved through the fusion of SF-LFM waveform with binary pseudo-random sequences, presents benefits such as noise immunity, cost-effectiveness, ease of implementation, and reduced power consumption.
