Stepped Frequency

Stepped frequency signal is an important high distance resolution signal, this property is realized by combining several pulse signal, so it is easy to be effected by targets radial motion. Here we analyzed how targets radial motion affects the synthesis HRRP, then a method of velocity measurement is provided, then compensation using the predicted velocity.

High Resolution Range Profile

This paper uses modern spectrum setimation to process stepped-frequency signals which have extracted to obtain high resolution range profile. This paper use FPE criteria and AIC criteria to estimate the order of AR model, and linear prediction is used to test the performance of AR model. Compared with conventional IFFT processing, the results of spectrum estimation is satisfactory, and the exact location of high resolution range profile is determined.
