The status and problems of airborne early warning radar detection technology at home and abroad are analyzed. In order to meet the requirements of resources optimization for airborne early warning radar detection, a processing architecture of air and sea simultaneous detection is proposed. Through the unified waveform, the unified signal processing architecture, and separate data processing, the simultaneous detection of air and sea is realized. Using genetic algorithm, a set of waveform parameters to meet the requirements of simultaneous detection of air and sea are designed. Aiming at the problem of low pulse repetition frequency clutter spreading full Doppler spectrum, the clutter suppression method based on space-time adaptive processing is also studied. Simulation results show that the proposed air and sea simultaneous detection architecture, waveform parameters and clutter suppressing method are effective.
