Abstract:
As a special signal, chaot ic signals have w ide prospect in the field of radar. A w aveform of chaot ic binary sequence is produced by means of the double scroll at tractor based on Wien bridge w ith a negat ive impedance converter in this paper. As the simulat ing result s of simulation program w ith intergrated circuit emphasis( SPICE) , the equilibrium of two values and the dist ribut ion of the run-leng ths is discussed by means of the rusults of SPICE. At last the ambiguity funct ion of the w aveform is analysed. T he results show that it has an approximate thumbtack shape, and has good range and velocity resolut ion, and good characteristics of elect ronic counter countermeasures ( ECCM) .
