Abstract

PURPOSE:To make it possible to utilize a low output amplifier and to reduce production cost by converting a signal restricted within a signal passage enabled band width of a chirp filter by a wide band signal forming means into chirp signal through the amplifier. CONSTITUTION:An output from an impulse signal generator 11 is supplied to a band pass filter 12 and only a frequency components within the signal passage enabled band width of the chirp filter 14 out of frequency components with an extremely wide band included in the impulse signal is passed. The passed signal is supplied to the chirp filter 14 through the amplifier 13 to convert the wide band signal into a chirp signal and output the chirp signal. In said constitution, the energy loss of the filter 14 due to signals with frequency components which can not be passed through the chirp filter 14 and the amplifier with a small output can be utilized, so that the production cost can be reduced.
