8、的发射装置那里，而用于支持车架及适用接收和反应来自处理器电子信号的驱动装置将按照处理器编程设计来移动车辆。 The receiver means preferably includes two spaced apart antennas with each operatively linked to a receiver. The receivers are preferably Super Heterodyne type or Near Zero IF type. The antennas are preferably spaced apart at a distance from each

9、 other. More preferably, the antennas are 25cm or more spaced apart from each other. 接收装置最好包括 2 根分开的天线，每根都分别能够与一台接收器连接。接收器最好是超外差接收器或是零中频 接收器。天线与天线之间最 好有一定的间隔距离。最好的距离是 25 厘米或者更远。 The two spaced apart antennas are preferably operatively connected to enable the processor to process the signal inputs to

10、 determine the location of the transmitter. The receiving antennas are preferably arranged with one antenna peak tuned and the other is dip tuned so that they are 90 degrees out of phase. The processor preferably can combine the two signals for a summed RSSI reading and measure a phase shift to dete

11、rmine the position of the transmitter means. 两根分开的天线最好有效的连接使处理器能 处理输入的信号来确定发射器的位置。接收的天线最好将一根调整到最高，一根调低，这样 2 根天线就能保持 90度的相反方向。处理器最好能结合 2 个信号的接收信号强度指示器（ RSSI）读数以及测量相位移来确定发射装置的位置。 Preferably the antennas have resonator coils that enable them to be dynamically tuned. With tuning the antenna, the predefi

13、l. The transmitter means is preferably portable. Alternately transmitter means may be a transponder which is activated on receiving a radio frequency signal from the vehicle and transmits a location signal back to the vehicle. Preferably the transponder is wearable and has a frequency between 200Khz

14、 to 8 Ghertz. More preferably the transponder has a frequency between 300 Khz and 500 Khz. 发射装置最好是发射信号而不是接收信号的转发器。发射装置最好是便携式的。代替的发射装置可以是一台转发器来激活接收来自车辆的高频信号并且返回传送一个定位信号给车辆。最好转发器可以配戴，且其频率在 200Khz 和 8 Ghertz 之间。最为理想的是转发器的频率在 200Khz 和 8 Ghertz 之间。 The transponder preferably has a plurality of capacitors

Alternately the frequency from the transponder may be modulated at a FSK keying rate of 500Htz with +/- 1 Khz frequency shift so that the receivers can identify their corresponding transponder. Furthermore the transponder preferably has a random number generator which is used to trigger transmit time so that transmissions are not synchronized to avoid the situation where multiple simultaneous transmissions are received by a receiver.
