The control device 312 loads all the parameters in the storage device 313, and sets the delay time duration of the transmission delay device 316 and the reception delay device 319, and the gain ratio of the reception device 310 according to the parameters. When the detection person pushes the cart 20 to trigger the distance encoder 40, the distance encoder 40 outputs an orthogonally encoded distance signal and transmits the signal to the control device 312. The control device 312 controls the emission delay device 316, the emission device 317 and the emitter 321 to emit controllable and delayed gaussian pulse signals. Meanwhile, the control device 312 controls the acquisition device 318, the receiving delay device 319, the receiving device 310 and the receiving electrode 322 to receive the rebounded signals, synthesize the signals and then sample the signals. The control device 312 uploads the digitized radar wave signals to the portable computer 10 through the communication device 311 for data analysis and display.
