The author of this note has been involved with the analysis of existing and future pulse doppler ambiguity resolution methods. The existing pulse doppler ambiguity resolution technique is supplied by R.C.A. and a future algorithm is presented by the author. The existing R.C.A. ambiguity resolution method has been tested and found to perform satisfactorily when the received data is scintillation free. These noise bursts produce extremely large estimation errors and poor convergence properties, this is due to their algorithm minimizing only range error, with a fixed time-invariant weight namely the number 1. The new algorithm using Kalman filter produces superior results. It embodies the simultaneous minimization of both range and range-rate errors and uses optimal time varying weights, namely covariance information.
