GHONGE & KUSHAL TUCKLEY Department of Electronics Engineering, Ramrao Adik Inst of Technology, Navi Mumbai, Maharashtra, India ABSTRACT A kalman filter as predictor for moving target devolved to detect & parameters like velocity, acceleration and displacement tracked. The approaches of target detection using barker code length with autocorrelation decide sharpness. The parameters of tacking target are predicted. At each epoch time average the sum of Diagonal element of covariance matrix for innovation is computed and compared with the dynamic ballistic missile. If the difference is high than predetermined level, the scale factor is set to update. Some computer result is carried out to compare the performance Kalman filter. KEYWORDS: Radar Target Identification, Additive Noise, State Measurement INTRODUCTION Radar posse’s unique and valuable attributes, there are some factors that can render information incomplete (03). The structure for the theory of Radar Target Identification (RTID).Radar signal processing consists of digital pulse compression using Barker code of sufficient length detect target. SNR estimation and ECM features like improving SNR in hostile environment (04). The approach is to estimate process noise variance by means of scale factor (04) (05). and, tracking algorithm using Kalman filter nonlinear target like ballistic and reentry space vehicles are presented. The simulation result demonstrates that the Kalgan filter is most robust to the sudden changes of the target. Target Detection The pulse compression correlates the receive signal to a delayed copy of that which was transmitted Barker sequences are unique with specific length can contains absolute values, 0, 1, for N bits in the sequence. and thus yield the best resolution for a given transmitted bandwidth (04) (05 that allowing secure enciphering Bits increases S/N ratio increases.
