Abstract :
The conventional simulation of target detection of PMMW (passive millimeter wave) radiometer assumes that the detector only has vertical movement. In this paper, based on the mathematical model of target signal of MMW radiometer, we derive the expression of the antenna temperature in the case that the beam centre is not on the axis, and the detector has horizontal and vertical motion. Simulation results are given, and signal characteristics are analyzed.
