“…Different from stationary radars, mobile radars are fixed on mobile carriers, in terms of installation methods, there are two kinds of platforms to fix radar: (1) gyrostabilized platforms (GSP) which can steadily follow systems referenced on local ENU (East-North-Up) frame [2]; (2) "unstabilized" GSP, namely, UGSP, directly fixed on platform and rotates with the platform simultaneously. GSP radar directly provides target coordinates (TCs) in the ENU reference frame.…”

For mobile radar, offset biases and attitude biases influence radar measurements simultaneously. Attitude biases generated from the errors of the inertial navigation system (INS) of the platform can be converted into equivalent radar measurement errors by three analytical expressions (range, azimuth, and elevation, resp.). These expressions are unique and embody the dependences between the offset and attitude biases. The dependences indicate that all the attitude biases can be viewed as and merged into some kind of offset biases. Based on this, a unified registration model (URM) is proposed which only contains radar "offset biases" in the form of system variables in the registration equations, where, in fact, the "offset biases" contain the influences of the attitude biases. URM has the same form as the registration model of stationary radar network where no attitude biases exist. URM can compensate radar offset and attitude biases simultaneously and has minor computation burden compared with other registration models for mobile radar network.
