Abstract

In view of the demand for multi-format modulated signals from multifunctional radar, a reconfigurable pulse compression signal generation scheme based on dual-parallel Quadrature Phase Shift Keying modulator (DP-QPSK) is proposed. In this scheme, the phase coded signal and linear frequency modulation signal can be switched by changing the encoding format of the input electrical signal without altering the link structure. To generate pulse signals with flexible and tunable carrier frequencies, optical filtering is not employed in this scheme. Simulation results demonstrate that the proposed scheme successfully achieves the switching between phase-encoded signals and linear frequency modulation signals, and the Peak-to-side Ratios (PSR) and Pulse Compression Ratios (PCR) of the generated signals closely approximate.
