Single-Ping Target Speed and Course Estimation Using a Bistatic Sonar

This paper focuses on estimating the two-dimensional (2-D) target-speed vector (course and speed) using a multistatic sonar that consists of one monostatic sonar and one bistatic receiver. The speed and course estimates are obtained after a single transmission. The theory on bistatic Doppler and 2-D target-speed vector estimation is first...

Target Doppler Estimation Using Wideband Frequency Modulated Signals

The topic of this paper is the design and performance analysis of wideband sonar waveforms capable of estimating both target range and Döppler using as few replicas in the processing as possible. First, it is shown that for conventional Döppler sensitive waveforms, for which the Döppler and delay are uncoupled, the Döppler accuracy is...
