A Ku-band four-sided two-dimensional digital array low-altitude early warning radar

Abstract

The present invention discloses a Ku-band four-sided array two-dimensional digital array low-altitude early warning radar, including a four-sided array radar shell, the phased array antenna array faces are all installed with an elevation angle of 15°, and the four phased array antenna array faces cover a range of 360°; a fan is arranged at the outer peripheral bottom of the four-sided array radar shell, and each of the wind nozzle components is connected and provided with a large air outlet, a right small air outlet, and a left small air outlet, and the large air outlets are four in total and the air outlet ends are respectively facing the corresponding sides of the chassis, and the air outlet ends of the right small air outlet and the left small air outlet on the same side are all facing the contact between the phased array antenna array face and the four-sided array radar shell on the same side. The present invention provides a Ku-band four-sided array two-dimensional digital array low-altitude early warning radar, which can achieve 360° all-round coverage, does not require a mechanical rotating mechanism, and has a built-in full coverage, targeted, and efficient heat dissipation and cooling, ensuring the long-term stable operation of the device in a high temperature environment, which is very worthy of promotion.
