The present invention relates to a kind of safety communicating method and system for controlling battle array based on frequency, method is comprising steps of (1) generates spreading code;(2) spreading code is spread to obtain transmitting array element sequence and submatrix serial number;(3) phase offset is added in each array element, and is modulated;(4) receiving end de-spreads the signal received, is demodulated using correlator;(5) signal after despreading is made decisions, and calculates the bit error rate.The present invention is by being introduced into the autocorrelation performance of spreading code in the direction modulation based on frequency control battle array, frequency control battle array is for phased array, it attached the frequency deviation for being much smaller than carrier frequency in each array element, the double control on angle and distance may be implemented on wave beam, precision is improved on angle and distance, the range that demodulates of receiving end is reduced, therefore, the safety of physical layer communication of higher precision may be implemented in the direction modulation technique based on frequency control battle array.
