  3. With the conditions of constant false - alarm probability and low signal - to - noise ratio, the signal - to - noise ratio can be improved by reducing the effects of background interference and random noise

    在恆虛警概率條件下，該演算法可以在低信噪比的情況下，減小背景干擾和隨機噪聲的影響，提高信噪比。
  4. As an aid to productivity, lead developers funnel communications between the wider project team and external organizations, and shield developers from noise and random interference in their daily schedules

    作為效率輔助手段，開發人員主管集中更廣的團隊項目與外部組織之間的交流，並保護開發人員避免噪音和日常安排中的隨機干擾。
  5. Disserted the principle of computer simulation of signal source of random moving multi - target, the methods of simulating two and three dimesion locuses of moving multi - target and simulating the interference of random noise. introduced the file format of the output parameters, the technique of data transformation and the method of software realization
