On the Impact of Unknown Signals in Passive Radar with Direct Path and Reflected Path Observations
Yicheng Chen, Rick S. Blum
We derive the closed form Cramer-Rao bound (CRB) expressions for joint estimation of time delay and Doppler shift with unknown signals with possibly known structure. The results ar…
