FIELD: radio engineering. ^ SUBSTANCE: coherent spaced diversity radio signal receiving and transmitting device includes signal shaping and processing module the radio frequency output of which is connected to input of adder the appropriate outputs of which are connected to N controlled delay lines respectively, each of which is connected to its antenna; the appropriate control diagram input is connected to each controlled delay line; the first information input of control system is connected to the appropriate output of signal shaping and processing module; the second information input of control diagram is connected to the module for determining the object location, and N antennae are installed with the pitch which meets the condition where R - maximum range of coverage of the device, - radio signal wave length, L - maximum linear size of the area in which antennae are located, N - natural number that is bigger than or equal to four. ^ EFFECT: improving spatial selectivity of the device as to range of coverage. ^ 4 dwg |
