Abstract

PURPOSE:To make transmission of radar signals possible using a communication circuit of small capacity by transmitting band compressed dates it is by a high speed digital circuit. CONSTITUTION:Input radar signals 6 are band compressed by a band compressing circuit 1 and made to parallel digital data 7 of N bits. Here, N is number of encoded bits determined by signal to noise ratio required to a radar signal transmitting device. The data 7 are speed converted and parallel series converted by an output converting circuit 2, and sent out to a high speed digital circuit 3. In receiving side, the data from the circuit 3 are processed reversely to the transmitting side. That is, the data are series parallel converted and speed converted by an input converting circuit 4, and the parallel digital data 8 are regenerated to original radar signals by a signal regenerating circuit 5 and supplied to each peripheral equipment. Thus, transmission of radar signals becomes possible even by a communication circuit of small capacity.
