Multisite Ultra-Wideband Radar Systems with Information Fusion: Some Principal Features

Detection characteristics, resolution capability, and target coordinates measurement accuracy of Multisite Radar Systems (MSRSs) consisting of Ultra-Wideband (UWB) radars are analyzed. Two types of UWB radars are considered: using short carrier-free pulses and using pulses with carrier frequencies. Target radial dimensions are assumed to be much greater than range resolution cells of UWB radars, so that we have target range profiles at each radar. Noticeable advantages of MSRSs with UWB radars have been shown; especially when range profiles of a target may be expected to be equal with respect to all radars.
