Problems solved by technology
[0002] Existing anti-aircraft missiles mainly rely on the seeker to identify the target and perform intelligent misses. After calculating the distance to the target, the detonation is delayed. The damage effect of this technical solution depends on the detection accuracy of the seeker and the measurement accuracy of the target speed. The real-time and damage effects are not ideal, and the fragmentation energy utilization rate for air targets is low

The invention discloses a missile-borne detection device based on a DBF. The device comprises a transmit-receive antenna group, a DBF processor, a signal processor, an integrated controller and a power supply assembly. The transmit-receive antenna group is used for transmitting and receiving 360-degree electromagnetic waves of the missile body and comprises a transmitting antenna array, a receiving antenna array, a T / R assembly transmitter and a T / R assembly receiver; the DBF processor is used for carrying out DBF processing on intermediate-frequency echo beat signals output by the transmit-receive antenna group, forming sum and difference beam data and sending the data to the signal processor; and the signal processor is used for controlling the working mode and the time sequence of a detection system, receiving the sum and difference beam data sent by the DBF processor, processing the data, completing target distance and angle measurement, and sending out a processing result througha corresponding interface. The device has the characteristics of high angle measurement precision, long detection distance, 360-degree circumferential detection, large dynamic range, high precision, high reliability and small size. In addition, the device works in a millimeter wave band, and has the characteristic of strong anti-interference capability.
Description
technical field [0001] The present invention relates to the technical field of detonation control system of anti-aircraft missiles, and specifically refers to a DBF-based missile-borne detection device, which is equipped in an air-defense missile system for real-time ranging and angle measurement, based on the precise distance to the apparent center of the target Orientation, timely output proximity detonation control command. Background technique [0002] Existing anti-aircraft missiles mainly rely on the seeker to identify the target and perform intelligent misses. After calculating the distance to the target, the detonation is delayed. The damage effect of this technical solution depends on the detection accuracy of the seeker and the measurement accuracy of the target speed. The real-time and damage effects are not ideal, and the fragmentation energy utilization rate for air targets is low. Contents of the invention [0003] The object of the present invention is to a...
