為了加強國家防禦，因此將雷達系統中作為發射訊號的脈衝波與自我注入鎖定技術結合。透過自我注入鎖定技術的優點，以消除靜止雜波帶來的影響，並提高系統靈敏度。本論文以雷達系統方式對其可行性進行初步實驗。
提出的脈衝自我注入鎖定雷達在閉迴路實驗中，能透過自我注入鎖定機制反映出不同的延遲時間。由IQ頻率解調器將回波訊號降至基頻，因此大幅降低對採樣率的要求。將解調後的回波訊號與開關的參考訊號進行互相關處理，兩組延遲線經過訊號處理的時間差與網路分析儀量測相符，這表示所提出的脈衝自我注入鎖定雷達在辨別不同延遲時間具有一定的效果。本論文也將脈衝壓縮雷達結合相位自我注入鎖定技術以實現拉伸處理，實驗結果也符合預期。由上述兩實驗可知，將自我注入鎖定技術應用於雷達系統有其發展可行性。

In order to enhance national defense, the pulse waves used as transmitted signals in the radar system are combined with self-injection locking technology. Leveraging the advantages of self-injection locking technology to eliminate the impact of stationary clutter, the system sensitivity is improved. This paper conducts preliminary experiments on the feasibility of the radar system in this manner.
The proposed pulse self-injection locking radar demonstrates the ability to reflect different delay times through the self-injection locking mechanism in closed-loop experiments. The IQ frequency demodulator lowers the echo signal to baseband, significantly reducing the sampling rate requirements. The processed echo signal after demodulation and the reference signal from the switch undergo mutual correlation processing. The time difference between the two sets of delay lines, as measured by a network analyzer, corresponds to the signal processing time, indicating that the proposed pulse self-injection locking radar has a certain effect in distinguishing different delay times. This paper also integrates pulse compression radar with phase self-injection locking technology to achieve stretch processing, and the experimental results are as expected. From the two experiments mentioned above, it is evident that applying self-injection locking technology to radar systems has developmental feasibility.
