New method for sorting radar signals
2010
To solve the problem existing in the sorting of the radar-signals under the high-signal-density and complex electromagnetic environment in the ARM,a new method of achieving sorting the radar-signals is presented.Using the coherent processor to pre-sort radar signals.In the main sorting,the modified PRI transform is used to measure the PRI of radar-signals.In the hardware,a method called non-uniform setting the width of PRI-box is put forward,which can save much running time of the algorithm to enhance the real-time performance of the system.The experimental results show that this sorting method has the advantages of high speed and preciseness,which both solves the sub-harmonic problem in the past histogram statistical method and overcomes shortcomings existing in the traditional PRI algorithm which cannot effectively sort jitter pulse trains.
