  1. In chapter 5 the jamming such as phase modulation noise, binary pseudo random sequence and multiple pseudo targets are discussed

    第五章對雷達干擾進行了闡述，主要的干擾信號有連續噪聲調相干擾、偽隨機碼噪聲干擾、多假目標干擾。
  2. Noise - the shadow samples are offseted from each other in a pseudo - random way, which artificially soften the borders of the shadows

    噪聲陰影采樣值的間值呈偽隨機數序列，將逼真地模擬陰影的邊界。
  3. Time domain noise is simulated by the mathematical pseudo uniform or normal random variable and coupled to deterministic signals such as rectangular ( rect ), triangular ( tria ), unit step exponential ( uexp ), even exponential ( eexp ), or gaussian ( gauss ) pulse voltages in finite number of time samples in finite time period

    用數學類真均勻或常態隨機變數模擬時域雜訊，與定然時域訊號如，方形、三角、指數遞減、或高斯等電壓脈波在有限時域?圍之有限個時域取樣結合。
  4. Pseudo - random noise code

    偽隨機噪聲碼
  5. Prn - pseudo random noise

    偽隨機噪聲
  6. However, the traditional spreading codes are usually deterministic pseudo - noise ( pn ) codes, which can be duplicated, potentially compromising the transmission security. then the time varying and random spreading codes are expected

    為了提高擴頻通信系統的抗干擾性、降低信號被截獲的概率，我們希望擴頻碼是隨機的、動態變化的。
  7. Traditional spread spectrum communication adopts pseudo - noise ( pn ) codes as spreading codes. however, pn sequence is fixed and periodic, which threatens the transmission security. self - encoded spread spectrum ( sess ) employs random spreading sequences that are extracted from the random information data, abandoning the fixed sequence

    傳統的擴頻通信廣泛採用偽噪聲（ pseudo - noise ， pn ）序列作為擴頻序列， pn序列具有類噪聲特性，但它實際上是確定的周期序列，容易被復制。
