Ultra-wideband Proximity Fuze Signal Processing Algorithms

Ultra Wide-Band Proximity Fuze is a new type of initiative proximity fuze that various countries are making research with it emulatively now. It has many advantages such as strong anti-jamming capability, highing resolution ration of the distance, small power cost and small volume and so on. It has a broad application perspective. In this paper, the key point lies in the signal processing of Ultra Wide-Band Proximity Fuze, we will find the appropriate algorithm and use the digital signal processor to process the echo signal. So the fuze will be effectted in normal and its tactical technology will be improved.The major work of the paper contains several points shown below:1. Introduced the characteristic, application and the develop environment CCS of the DSP chip. We chose the 2401A DSP chip of TI as the development object.2. Introduced that DSP hardware circuit's each constituent, including the chip of clock, Digital to Analog converter, voltage stabilizer and so on. Then complete the design and debugging of the circuit.3. Introduced the data acquisition system, in order to decide which algorithm will be selected, we use it to acquire the echo signal, and then analyses the property of the signal acquired. Then, we introduce the theory of the filter, growth rate of amplitude and interrelation algorithm. By using the MATLAB simulation software to simulate the validity of the algorithm.4. Introduced the implementation procedure of the each algorithm, we use the integrated develop environment and through DSP electric circuit to test and verify the validity, applicability and reliability of the algorithm.
