[Abstract](4656) [HTML](0) [PDF 0.00 Byte](6) [Cited by](20)

Abstract:
In the electronic reconnaissance and countermeasure field, it is more and more important to analyze the in-pulse character of complicated signals. The major characteristic of wavelet transform is,by means of continuous change of scale from wide to narrow, wavelet transform can gradually focus on any detail of analyzed object. On the base of wavelet-ridge method, extracting the instantaneous frequency of radar signal to obtain signal's in-pulse small character is studied in this paper. The improved wavelet-ridge method is put forward by aiming at the shortage of wavelet-ridge method. A set of linear frequency modulation data is simulated and studied. The data is received by some electronic counter-reconnaissance equipment and have big product of time width and bandwidth, and the simulation results proved the advantages of improved wavelet-ridge method.

Abstract:
It is often desireable to widen the interference null width in an adapted pattern to impart robustness into the realized adapted pattern in some real environments. In this paper, an adapted pattern null widening method is derived from a statistical model. It can reject effectively interferences when the perturbation of interference locations occurs. Moreover, this method is simple and easy processing. Computer simulation results are presented for illustration.

[Abstract](4829) [HTML](0) [PDF 0.00 Byte](1) [Cited by](18)

Abstract:
Coherent correlation radar clutter is mostly generated by extending zero memory nonlinearity (ZMNL) for corresponding incoherent coefficients clutter. The premise of ZMNL is the nonlinear relation between the correlation coeficients before and after nonlinear transform is known. But for the coherent correlation tributed clutter, such a nonlinear relation is difficult to find. In this paper, the simulation model of coherent correlation K distributed clutter using spherically invariant random processes (SIRP) is presented and as an example, the Gaussian spectrum clutter is simulated the results proved the validity of this scheme.
