Array Signal Synthesizer Technology Based on Delay Filter Arithmetic
Fei Huang · Dianzi qijian · 2007
Accurately delaying the reference signal with high resolution is the key point in array signal synthesizer. Firstly, the basis principle and method of array signal synthesizer are introduced.According to the characteristic of array signal, the synthesizing technology based on delay filter arithmetic is discussed.The advantage of the method is that we can obtain the accurate delay with high resolution even though the sample frequency of D/A is low. It shows by simulation that the method is simple, low-calculation, high-accurate and very suitable to use in array signal synthesizer.
