摘要: A pulse expander-compressor for magnifying the range-doppler-coupling effs that accompany use of frequency-modulation derived phase coded compressors in order to accentuate doppler-coupling velocity effects on target echoes. The foregoing magnification is accomplished by generating a doppler tolerant polyphase waveform with equal time spaces inserted between successive code elements make difference first and last independent number involved. These may be variable allow any desired radial produce 2π. implemented replacing each delay t c compressor input-signal expansion circuit set N , associated switches, switches permitting element connected or bypassed, as desired. time-dispersion likewise modified its Mt delays which independently connectable bypassable.
