Single-Pulse Estimation of Target Velocity on Planar Arrays
conference paper
Doppler velocity estimation in pulse-Doppler radar
is done by evaluating the target returns of bursts of pulses. While
this provides convenience and accuracy, it requires multiple
pulses. In adaptive and cognitive radar systems, the ability to
adapt on consecutive pulses, instead of bursts, brings potential
performance benefits. Hence, with radar transceiver arrays
growing increasingly larger in their number of elements over the
years, it may be time to re-evaluate how Doppler velocity can
be estimated when using large planar arrays. In this work, we
present variance bounds on the estimation of velocity using the
Doppler shift as it appears in the array model. We also propose
an efficient method of performing the velocity estimation and we
verify its performance using Monte Carlo simulations.
