| description | PROBLEM TO BE SOLVED: To obtain an SNR improvement effect by performing target detection with respect to an area suitable for long-time integration and undetected in conventional CINT and NCINT.SOLUTION: The present invention comprises: a data reception unit 1 for receiving data; a CPI separation unit 2 for performing pulse compression on the received data separately for each CPI; a CPI integration unit 3 for performing, for each CPI, Doppler filtering by CINT on the data that was separated for each CPI and pulse-compressed; a range walk compensation unit 4 for compensating, for each Doppler filter, the data that was Doppler-filtered for each CPI for range walk; an inter-CPI integration unit 5 for performing CINT and NCINT between CPIs on the data that has been compensated for range walk independently of each other; a synthesis unit 6 for synthesizing the CINT result and NCINT result by using a coupling probability density function; and a CFAR processing unit 7 for performing CFAR processing on the synthesized data by using the cumulative distribution function of the coupling probability density function.
【課題】長時間の積分に適し、従来のＣＩＮＴとＮＣＩＮＴにおいて未検出であった領域についても目標検出を行うことで、ＳＮＲ改善効果を得る。【解決手段】データを受信するデータ受信部１と、受信されたデータをＣＰＩ毎に振分けてパルス圧縮を行うＣＰＩ振分け部２と、ＣＰＩ毎に振分けられパルス圧縮されたデータに対し、当該ＣＰＩ毎にＣＩＮＴによるドップラーフィルタ処理を行うＣＰＩ積分部３と、ＣＰＩ毎にドップラーフィルタ処理が行われたデータに対し、ドップラーフィルタ毎にレンジウォークを補償するレンジウォーク補償部４と、レンジウォークが補償されたデータに対し、ＣＰＩ間でＣＩＮＴおよびＮＣＩＮＴを独立に行うＣＰＩ間積分部５と、ＣＩＮＴ結果およびＮＣＩＮＴ結果を、結合確率密度関数を用いて合成する合成部６と、合成されたデータに対し、結合確率密度関数の累積分布関数を用いてＣＦＡＲ処理を行うＣＦＡＲ処理部７とを備えた。【選択図】図１ |
