近炸引信

On the background of the new rocket depth charge multifunction fuze, the signal processing circuit of ultrasonic detection receiver is studied. The aim of this dissertation is to improve the performance of the receiver.

本文以火箭深弹新型多作用体制引信为应用背景，主要就引信声近炸模块主动超声波探测接收机信号处理电路进行了研究，目的是提高接收机对回波的处理能力，从而提高引信探测目标能力和近炸精度。

Firstly the theory of the ultrasonic proximity module in new fuze is analysed. The factors which affect performance of the proximity fuze are studied.

首先分析了火箭深弹新型引信声近炸模块的工作原理，对影响引信声近炸性能的因素作了研究，着重研究了增强超声波探测收机性能的关键技术，即接收机自动增益和信号处理技术。

The HQ-7 missile is armed with a high-explosive fragmentation warhead, initiated by with a proximity fuse.

HQ-7导弹装有一个高爆破片弹头，采用近炸引信启动。

The discrepancy was so great it has led military historian Max Hastings to wonder how in the world "could American and British industries produce a host of superb aircraft, an astonishing variety of radar equipment, the proximity fuse, the DUKW , the jeep yet still ask their armies to join battle against the Wehrmacht equipped with a range of tanks utterly inferior in armor and killing power?"

双方坦克差异如此巨大，令军史学家马克斯·哈斯廷斯特惊叹，为什么在这世界上&美英工业能制造大批巨型飞机，令人眼花缭乱之雷达，近炸引信，水陆两栖车，吉普，还让军队与装甲、杀伤力方面具有绝对优势之德军坦克交战对抗？&

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
