| Abstract: | The paper introduces the sequential algorithm for joint detection and estimation on the basis of sufficient statistics and reproducing probability density function. The new algorithm is used in the case of joint detection and estimation of signal known except for phase in Gaussian noise, which is a classific problem in radar or active sonar. The simulation results show that the new algorithm performs better than the traditional ones. |
