Abstract:

The range estimation problem is generally solved by assuming a low order target mass center motion description such as constant velocity or constant acceleration or by postulating a well defined manuever. Assumptions are often made that require the receiver signal associated with a well tracked target to have a narrow bandwidth. These assumptions are unreasonable for certain range estimation problems. An approach general enough for use with virtually any pulsed narrowband transmitter waveform and a variety of finite parameter descriptions of time varying target range and cross section is developed. The associated best approximation problem is nonlinear but has a special structure which permits a computable solution in applications of interest involving thousands of unknowns. An Appendix provides an example of estimating a polynomial propagation delay from observations of the radar receiver signal. Keywords include Range estimation Receiver signal Polynomial propagation delay Narrowband radar Best approximation and Target range.
