雷达信号环境模拟器在模拟复杂电磁信号环境时,会产生大量脉冲丢失,这与实际战场环境不符,同时对电子侦收也存在一定影响。采用直接数字合成(DDS)技术可生成任意波形,解决脉冲丢失问题。
雷達信號環境模擬器在模擬複雜電磁信號環境時,會產生大量脈遲丟失,這與實際戰場環境不符,同時對電子偵收也存在一定影響。採用直接數字閤成(DDS)技術可生成任意波形,解決脈遲丟失問題。

When the radar signal environment simulator is used to simulate the complicated electromagnetic signal environment,it may miss a lot of pulses,which is inconsistent with the actual battlefield environment, at the same time the electronic reconnaissance and reception will be affected. This article uses the direct digital synthesis (DDS) technique that can generate arbitrary waveform to resolve the problem of pulse missing.
