The present invention discloses a coarse digital elevation map-based InSAR (interferometric synthetic aperture radar) absolute phase fuzzy estimation method. The main objective of the invention is to solve the problem of requiring ground accurate control points and the problem of complicated calibration computation in real-time digital elevation map generation of an existing radar. The method includes the following steps that: 1) the reference average height of a target scene is determined according to the coarse digital elevation map of the target scene; 2) a scene center slope distance is estimated according to the reference average height of the target scene; 3) the unwrapping phase and absolute phase of the scene center reference point are calculated; 4) the absolute phase fuzzy number of the whole scene is calculated according to the unwrapping phase and absolute phase of the scene center reference point; and 5) a real-time digital elevation map is obtained through inversion according to the absolute phase fuzzy number of the scene. With the coarse digital elevation map-based InSAR absolute phase fuzzy estimation method of the invention adopted, the absolute phase fuzzy number of a ground scene according to which no ground accurate control points exist and height changes sharply, can be estimated correctly and quickly. The method can be applied to the real-time signal processing system of an airborne radar.

The invention discloses a method for constructing a distributed heterogeneous processing framework, which comprises the following steps: a publishing module sends request data and blocks the current thread by subscribing to the first message; a service scheduling module receives the request data and encapsulates it into an intermediate file package And write to the cache module and block the current thread by subscribing to the second message; the calculation engine module calls the intermediate file package and loads the corresponding data according to the configuration data and processes it, and stores the processed final file package in the cache module; the calculation engine module dispatches to the service The module publishes the second message; the service scheduling module receives the second message and recognizes the second end mark, unsubscribes the second message; the service scheduling module publishes the first message to the publishing module; the publishing module receives the first message and recognizes the first end mark, Unsubscribe the first message; the publishing module reads the final file package from the cache module to obtain the data processing result; the invention improves the real-time processing efficiency on the data line and the storage capacity of the message.

The invention discloses a hierarchical data processing method for a large-scale real-time rainfall automatic observation station based on dynamic interpolation. The hierarchical data processing methodcomprises the following steps: step 1, receiving and processing reported data of national automatic observation stations in real time; step 2, judging an abnormal value; Step 3, equal time period processing; Step 4, screening and eliminating error values; And 5, performing interpolation calculation on the basin surface rainfall.
