N2 - We proposes and verifies a method for generating phase-coded microwave pulse signals based on Active Mode-Locking Optoelectronic Oscillator (AML-OEO). With the help of the AML-OEO, this scheme utilizes a phase modulator driven by phase-coded signals, where the duration of each voltage polarity code is the same as the OEO loop delay, generating phase-coded coherent microwave pulse trains. Such signals have the advantage of a large time-bandwidth product, which can balance the detection range and range resolution of radar, while also possessing characteristics such as anti-interference and low interception. In experiments, we obtained the phase-coded microwave pulse sequences using square waves and 7-bit Barker codes respectively.
