PASSIVE ARRAY TRACKING OF A CONTINUOUS WAVE TRANSMITTING PROJECTILE.

Research output: Contribution to journalArticlepeer-review

Abstract

Differential Doppler measurements by a passive array are used to track an unstable continuous wave (CW) source moving in a ballistic trajectory, e. g. , a projectile carrying a proximity fuse. The ballistic equations of motion couple frequency measurements at various sections along the track with the track parameters at any arbitrary time, e. g. , at impact. A nonlinear weighted least-square method is used to estimate the track parameters, and the resulting error covariance matrix is derived.
