Radar Waveform Design Based on Linear Frequency Modulation Signal

Abstract

W With the continuous development of electronic countermeasure technology, radar is increasingly threatened by electronic interference, anti-radiation weapons, stealth targets, and low-altitude penetration in the current battlefield. In this context, low intercept probability radar emerges as the times require. The essence of low intercept probability radar is that the maximum effective range of the radar is greater than the maximum detection distance of the enemy reconnaissance receiver. Radar waveform design is one of the important measures to improve the performance of radar LPI. The radar's transmit waveform directly affects the performance of the radar. This paper mainly introduces the radar waveform design based on linear frequency modulation and the fuzzy function of the linear frequency modulation radar waveform, which provides a certain reference for radar waveform design.
