本文介绍了两种极座标示向的实用研究成果。通过UHF干涉仪测向终端极座标示向的研究与试验,对如何满意地实现较高的精度(<1°)、分辨力(0.5°)、速率(10ms),较低的功耗(8W)、低压源(±1 2V、±38V),较小的体积、重量等指标之思路、方法,进行了试验和探讨。其中,设计合适的平衡检流器、集成运放的“有源带通滤波器”和高压集成运算放大器等,发挥了积极作用。通过内外场试验,实际考验了示向机器的可靠性、稳定性、抗震性、实用性。通过了技术鉴定。
This article describes the practical results of two polar coordinates. Through the research and test of the UHF interferometer direction finder polar coordinates, how to achieve high accuracy (<1 °), resolution (0.5 °), speed (10ms), low power consumption ), Low pressure source (± 1 2V, ± 38V), smaller volume, weight and other indicators of the ideas and methods were tested and discussed. Among them, the design of a suitable balanced current detector, integrated operational amplifier “active bandpass filter ” and high voltage integrated operational amplifier, played an active role. Through the internal and external field tests, the actual test showed the reliability of the machine, stability, shock resistance, practicality. Passed the technical appraisal
