摘　　要：本文提出一种采用电消隙技术减小回程误差的方法。通过对回程误差进行分析,从结构和电路两方面分别介绍减小回程误差的措施,并结合船载雷达设备重点对电消隙技术进行研究分析。与传统的单纯机械消隙相比,电消隙技术显著提高了船载雷达的测量精度。The article submitted a new technology of circuit away gap to reduce hysterisis error. The article analyzed hysterisis error, and investigated the technique of reducing hysterisis error from structure and circuit.Combined with shipborne radar equipment it analyzed the technology of circuit away gap with emphasis. Compared with traditional simple mechanical technology, circuit away gap technology can raise the measurement accuracy of shipborue radar obviously.
