受地球曲率的限制,机载对海雷达相对舰载或地面雷达,对海面目标和低空飞行目标的作用距离更有优势。机载对海雷达已经历了三个发展阶段,从完全机械扫描体制发展为二维相扫体制。机载对海雷达正面临小目标探测、作战情报质量和复杂电磁环境三大挑战。文中提出了机载对海雷达的发展趋势为提升小目标探测能力、优化情报质量及推广有源相控阵体制的应用。

Limited by earth curvature, airborne sea surveillance radars have the advantage of operation range for sea surface targets and flying targets at low altitude over ship-borne radars and ground based radars. Airborne sea surveillance radar experiences three development phases. It develops to two-dimension phase-scan system from completely mechanical scan system. Currently, airborne sea surveillance radar is facing three challenges: small targets detection, quality of operational intelligence and complicated electromagnetic environment. Based on these, development trends of airborne sea surveillance radars are presented in the article, i.e. improvement of detection to small targets, optimization of intelligence quality and application spread of active phased array system.
