Simulation of Linear Frequency Modulated (LFM) Pulse Signals

LFM signals are extensively utilized in pulse compression radar systems. By leveraging the large bandwidth and long pulse characteristics of linear frequency modulation, wide pulse transmission is employed to increase average transmit power, ensuring sufficient operational range. During reception, corresponding pulse compression algorithms are applied to obtain narrow pulses, thereby enhancing range resolution. This effectively resolves the conflict between radar detection range and range resolution. Beyond improving radar system resolution and detection capabilities, pulse compression technology also enhances anti-jamming performance and flexibility, meeting the requirements for multifunctional and multi-mode radar operations.
