Take integrity of object information into condition, a two - dimension signal processing method which can make a measurement of the target ’ s speed as well as the range is brought forward at the basis of waveform parameter design. and simulation in the background of hf multi - object with noise is taken. a comparison of signal properties, processing and antinoise detection performance is taken between mcpc and another two high range resolution radar signals : single carrier pulse coded signal and step frequency pulse coded signal
考慮到目標信息提取的相對完整性，以高頻雷達為背景，在對多載波相位編碼脈沖串信號參數設計的基礎上，推導了三種多載頻相位編碼脈沖串信號的距離速度二維處理過程並相應的對多目標噪聲環境進行了模擬;將多載波相位編碼信號與另外兩種距離高分辨信號:單載頻相位編碼信號和相位編碼階梯跳頻信號，在信號特性、處理過程和抗噪聲特性方面進行了對比;本文從理論上為多載波相位編碼信號的波形設計和分析、信號的處理打下基礎。 -
This article works over a mathod named large step fast acquisition to capture the pn code in the receiver, which was originally put forward for the acquisition and synchronization of long pn code under the condition of low signal to noise ratio ( s / n )
本文主要研究了大步進快速捕獲法，該方法是針對低信噪比下長擴頻碼的捕獲和同步問題提出的。 -
To accept the current signal from high negative voltage circuit, the analog ground is raised to a certain positive voltage, which makes it possible for the signal amplitude to be compressed at the same time of its polarity reversion. a pi control program special for laser gyro current control is brought forward according to the conventional pid control method, in which the control signal is figured out corresponding to the difference between the sample and the reference value by turn of proportion - short step integral - long step integral. and at the end of this paper, a comparison of system performance on different conditions is made and the key elements influencing system performance are educed
