普莱西公司的AR320雷达是一部工作在E/F频段的远程三座标防空雷达。脉内频扫可以对每一个发射脉冲用一个扫描笔形波束在发射和接收时工作于仰角的整个规定覆盖区。波束组是由一个低旁瓣平面阵列天线经频率/相位扫描后产生的。仰角和方位上都具有双向杂波抑制能力,且能保持高数据率。它的主要特点是:高平均功率的两级发射机,高增益的笔形波束天线、窄的压缩脉冲、大动态范围恒虚警率接收机、频率捷变和多卜勒处理。由于具有这些特点,每一次天线扫描都可提供远距离检测和精确的高分辨的三座标点迹信息并具有高的抗干扰性。与站上配备的二次雷达配合使用时,点迹输出可以是一次的、二次的或一次/二次相关的。一部单独的电子干扰估计接收机不断地对电子干扰环境进行监测,给操作员显示器和各种功能的电子反干扰自动控制提供数据。 Playsi’s AR320 radar is a long-range, three-coordinate air defense radar operating in the E / F band. An intra-frequency sweeping sweep can use a swept pencil beam for each transmit pulse throughout the defined coverage area at elevation for both transmit and receive. The beam group is generated by a low sidelobe planar array antenna after frequency / phase sweep. Both bi-directional clutter suppression is available at elevation and azimuth, and high data rates are maintained. Its main features are: high average power two-stage transmitter, high-gain pen beam antenna, narrow compression pulse, large dynamic range constant false alarm receiver, frequency agility and Doppler processing. Because of these features, each antenna scan provides far-field detection and accurate, high resolution, three-coordinate trace information with high immunity to interference. When used with a secondary radar equipped on the station, the spot trace output can be once, twice or once / twice related. A single electronic jammer receiver continuously monitors the electronic jamming environment and provides data to operator displays and electronic anti-jamming automatic control of various functions.
