摘　　要：Eight families of Costas arrays with ideal cross-coincidence are algebraically constructed under the assumptin that the vertical shifts are appropriately bounded.These Costas arrays are useful for designing multiple Costas wavforms with small crossambiguities, if the potential Doppler shifts are restricted to a small portion of the wavform bandwidth.Eight families of Costas arrays with ideal cross-coincidence are algebraically constructed under the assumptin that the vertical shifts are appropriately bounded.These Costas arrays are useful for designing multiple Costas wavforms with small crossambiguities, if the potential Doppler shifts are restricted to a small portion of the wavform bandwidth.
