Joint 2‐D LFM Modulation and Mismatched Filter Design in Dual‐Function Radar‐Communication System
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper proposes a joint 2‐D LFM modulation and mismatched filtering design for military‐grade dual‐function radar‐communication systems. The novel scheme modulates data onto both the initial frequency and chirp rate of LFM pulses, boosting data rates whilst preserving the constant‐envelope property critical for high‐power transmission.
