Abstract: Hopping sequences used in anti-jamming hopping communication ought to have a longer period, therefore the partial and dynamic properties of balance and Hamming correlation are more essential in practical hopping sequences application. For the sake of anti-forecast two new design desires of sensitivity of hopping sequences to time of date(TOD) and address code are put forward. To check carefully partial and dynamic properties of balance and Hamming correlation is necessary for traditionary hopping sequences. The traditionary method of simple exclusive OR output sequences by address code is not available for requirement of anti-forecast. It is necessary to mix address code in transform process of input TOD as block cryptogram. To base on aforementioned understand we propose that partial and dynamic property of balance and Hamming correlation and two requirements of anti-forecast ought to be important targets of technical performance in hopping sequences application.

Key words: balance, hopping communication, Hamming correlation, anti-forecast
