Abstract :
In Good resolution is one of the criteria for measuring the performance of a radar system and it can be achieved with low Band- width. The radar rang depends on the energy it sends. With using pulse compression techniques, the energy of a wide pulse and resolution in the range corresponding to a narrow pulse can be simulatuesly held. The basis of the pulse compression radar is on the matched filter and Autocorrelation function. In the radar, the return echo of the target is actually a delayed time prescription or Doppler shifted signal transmit. The matched filter correlates between received signal and the version of the sending code. The matched filter output in addition to having a main lobe, also includes a sequence of side lobes. These sidelobes cause to increase the probability of false alarm or masking the small target, beside large targets with high sidelobe level. Mismatched filters using weighting function for reduction the level of the sidelobes, with increase the length of filter. In this paper suggests a parallel structure that added advantage of matched filter and mismatched filter simulatuesly.
