Abstract

The paper considers the possibilities for shipborne radar (λ = 4.5 cm) to detect over-the-horizon objects in higher refraction conditions. It is shown that, due to antenna pattern adaptation to high refraction coefficient gradients in the troposphere lower layers, the radar receiver output signal-to-noise ratio can increase by 20-23 dB.
