Embodiment

Below in conjunction with accompanying drawing, the present invention is done detailed explanation.

As shown in Figure 1, a kind of based on soft data support target estimated signals treating apparatus, comprise that interconnective target device 3-4, multilevel objectives estimating system, soft data support base management system and external unit 3-7; In the said multilevel objectives estimating system, signal processing module 3-1, stimulating module 3-2, receiving and transmitting front end module 3-3 and receiver module 3-5 connect to form a loop successively and are connected with same interface control module 3-6 respectively; The external target device 3-4 of said receiving and transmitting front end module 3-3; The external soft data of said interface control module 3-6 is supported base management system 2-4 and external unit 3-7.

Data flowchart is as shown in Figure 2 among the present invention.When carrying out passive assessment; The modulation signal that echo signal source 2-1 sends directly converts digital signal to through receiving cable 2-2 and delivers to and carry out signal Processing 2-3 among the signal processing module 3-1, and signal processing module 3-1 accomplishes target by the support of outside soft data storehouse 2-4 and estimates to resolve; If active sensor then need be used transmission channel 2-5, accomplish estimation to target through the closed-loop process that emission earlier receives again.

As shown in Figure 3; Said multilayer level target estimating system inside also comprises three functional modules such as information analysis characteristic module 1-1, characteristic vector sequence matching module 1-2 and semantic information evidence judging module 1-3, and said soft data is supported to comprise and these three functional module characteristic of correspondence data knowledge library module 1-4, priori features vector set library module 1-5 and semantic constraint condition library module 1-6 in the base management system.

Like Fig. 4, shown in Figure 5; The chip that said signal processing module 3-1 comprises FPGA, DSP, DSP external memory bus and has transmitting-receiving agreement, level conversion, isolation and driving function; Exchange channel data and control signal and clock signal is provided for DSP between said FPGA and the chip; Exchange agreement data between said DSP and the chip, said signal processing module 3-1 is connected with transmission channel, receiving cable and external unit 3-7.

FPGA is responsible for providing the channel module interface, and the transceiver channel data are also accomplished coding and decoding, transmit control signal to channel module, for DSP clock are provided simultaneously; The management, multilayer level target that DSP is responsible for the device interior soft data estimate judgement and and external unit between message exchange.

FLASH, SDRAM, FPGA in the signal processing module 3-1 all are hung on the DSP peripheral hardware memory bus, conduct interviews through data/address bus.FLASH is used to store target signature knowledge base data, and SDRAM is used to store when subtask required target feature vector collection and constraint condition database data, also needs under the duty target signature knowledge base data are moved to SDRAM from FLASH, to promote operation efficiency.Signal processing module 3-1 manages through DSP/BIOS operating system, realizes that command analysis, task trigger, State Control.

Signal processing module 3-1 operational scheme is as shown in Figure 6: module powers on and promptly carries out module initialization 5-1; Get into waiting status 5-2 subsequently; When receiving corresponding task order 5-3, target is estimated that 5-4 and result report 5-5, get into once more after task is accomplished and wait for 5-2.

Module initialization has comprised that module hardware initialization and soft data support the configuration in storehouse, its operational scheme such as Fig. 7: carry out hardware initialization, comprise the initial configuration 6-1 to FPGA, DSP and related peripheral chip; Read the external knowledge storehouse 6-2 of version number, if with FLASH in the inconsistent 6-3 of knowledge base version, then need from the outside admission knowledge base data and data the FLASH upgraded 6-4; Move 6-5 to the knowledge base data from FLASH to SDRAM; Admission set of eigenvectors and constraint condition stock go into SDRAM 6-6 from the outside again; Accomplish pre-service 6-7 (comprising calculating such as feature weight) at last, thereby accomplish use configuration soft data based on the relevant global variable of algorithm in soft data storehouse.

Carry out target among the signal processing module 3-1 and estimate operational scheme such as Fig. 8 of processing: receive that FPGA deciphers, parses signal pulse series 7-2 to signal from 7-1 after the A/D data in echo signal source; DSP supports 3 levels of carrying out among Fig. 1 through the soft data among the SDRAM and estimates judgement; Accomplish element extraction by feature knowledge storehouse 7-3 respectively and resolve 7-4; Accomplish proper vector coupling 7-6 by extraordinary vector set storehouse 7-5, accomplish information semantic judgement 7-6 by constraint condition storehouse 7-7; Finally obtain estimated result to target.
