Pulse compressing device

Abstract

Abstract PURPOSE:To eliminate the influence of the phase distortion of a pulse compressing device by detecting phase distortion data on a transmission and a reception part, and performing pulse compression so that those data are compensated. CONSTITUTION:The pulse compressing device 1 performs pulse compression and digital processing and consists of a quantizing device 8, pulse compression part 5, matched filter generation part 6, data processing part 7, and group delay measuring device 2. The quantizing device 8 converts a receive signal from an input terminal 9 into digital data, which is supplied to the pulse compression part 5. The group delay measuring device 2 measures thr group delay characteristics of a receive monitor signal from an input terminal 10 which has phase distortion at the transmission part and reception part and consists of a timing generator 4 and a frequency counter 3. Measurement data from the device 2 is sent to the data processing part 7 to calculate phase data approximately, and phase distortion characteristic data is sent to the matched filter generation part 6. The pulse compression part performs correlative arithmetic and outputs compressed pulses.
