The main task of waveform -generation of X -band protable battlefield reconnaissance radar is not only satisfies the index of radar system but also how to reduce its volume, weight and power consumption. The low power consumption, miniaturization and LPI design method of a waveform - generation of protable battlefield reconnaissance radar is introduced. The design of module integration and MCM can reduce its volume and weight of waveform- generation system,apply the circuits of analogy and phase locking can reduce its power consumption, apply the form of binary- phase Code can improve ifs LPI performance,its output power of waveform- generation system≥10 W,improvement factor ≥45 dB, total power consumption ≤7 W, weight≤ 1.3 kg, volume≤ 140 × 130 ×30 mm^3. It is satisfied the demand of system.
