摘要： The specification discloses a semiconductor magnetic modulator for use with a moving target indicator radar transmitter and which utilizes a plurality of charging capacitors for receiving charging current from a direct current power source and discharging in parallel. Silicon controlled rectifiers are connected to each of the charging capacitors and are operable to triggering signals to cause said capacitors to discharge at a predetermined time. A de-Q-ing circuit is connected to each of the charging capacitors in order to sense the voltage level across the capacitors and to dissipate voltage above a predetermined threshold level. The charging capacitors discharge through a hold-off inductor and through a switching transformer to a pulse forming network including a second charging capacitor. Compression occurs in the pulse charging network and a resulting high power modulator pulse is applied from the network to a klystron power tube in a moving target indicator radar transmitter. The power supply for the modulator utilizes an SCR bridge A.C. to D.C. convertor. An automatic delay circuit is also provided in order to provide a stable radar modulator trigger signal to the modulator circuit.
