Abstract :
The bit-error probability is evaluated for a hybrid chirp/direct sequence (DS) spread-spectrum communication system. The received signal is received in Doppler; the channel is contaminated by a pulsed barrage jammer with a varying duty factor. Moreover, the DS correlation loss due to imperfect code synchronization is taken into account. The tradeoffs involved in dividing the total RF bandwidth into the DS and chirp bandwidths to combat both the jamming and the Doppler are discussed
