The range and velocity measurement performance of DS/FH hybrid spread spectrum signal with the interference

Under the new DS/FH hybrid spread spectrum signal system, the measurement performance with the interference is presented. The DS/FH system model was established, and analyse the characteristics of three kinds of interference signal, which are partial-band noise jamming (PBNJ). wide-band noise jamming (WBNJ) and additive white gaussian noise(AWGN). The performance of different tracking loops is analyzed under the background of TT&C System. Then through simulation to know the range and velocity measurement performance.
