Purpose of the paper is to present a solution for the target height estimation problem for multi-frequency multi-static passive radar. Aim of the proposed estimation strategy is to provide 2D passive sensors, which measure only bistatic range and Doppler, with target height estimation capability via the simultaneous exploitation of multiple FM transmitters (88–108 MHz). Results achieved with simulated...
In the present paper, we derive the Cramer-Rao Lower Bound (CRLB) with uncertain observations, namely for Pd<;1, for the 2D position measurements of a multistatic passive radar, to optimize the geometry of the system. This is an extension of the enumeration method CRLB to the multisensor case, where it is considered that the multiple receivers could detect or miss the target independently of one...
Introduction and main concepts: An increasing interest in passive surveillance systems can be observed in last period. The key idea, which is also common to other non-radar applications, is to conveniently exploit opportunity signals, as analogue FM transmitters or Digital Video Broadcasters to detect and/or tracking targets [1–3].
In this paper, starting from the monostatic radar ambiguity function we derive the bistatic ambiguity function and the Cramer-Rao lower bounds (CRLB) of range (time delay) and velocity (Doppler shift) of a radar target in the case of linear frequency modulated (LFM) pulses embedded in white Gaussian noise. Moreover, we compare monostatic and bistatic CRLBs as a function of number of integrated pulses,...
