Small targets, including pedestrians, cycles, animals, and on-road debris, are significantly vulnerable and critical things on the road. Automotive millimeter wave radars must accurately identify these vulnerable and dangerous targets to avoid serious traffic accidents. Although fast chirp modulation (FCS) frequency modulated continuous wave (FMCW) multiple input multiple outputs (MIMO) radars (FCM-FMCW-MIMO radars) can resolve multiple targets with enough different ranges, velocities, and angles with large target sizes. However, current automotive millimeter wave radars cannot discriminate small targets on spatial spectra that estimate target angles from inherent sidelobes. These sidelobes are referred to as ghost peaks. This paper proposes a method to discriminate small targets from ghost peaks by introducing thinned antenna arrays and large targets canceling on antenna element space. Experimental results using a millimeter wave radar validate the proposed method.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌: \u003c\/strong\u003e\u003ca href=\"\/products\/ieej-20250228c00701\"\u003e2025年3月3日-2025年3月4日通信研究会\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ: \u003c\/strong\u003e31-34 p\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e英語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ: \u003c\/strong\u003e2,722 Kバイト\u003c\/p\u003e","brand":"IEEJ-P10","offers":[{"title":"冊子印刷（一般価格660円\/会員価格440円） \/ A4 \/ 4","offer_id":46408136949999,"sku":"IEEJ-20250228C00701-007-PRT","price":660.0,"currency_code":"JPY","in_stock":true},{"title":"PDFダウンロード（一般価格330円\/会員価格220円） \/ A4 \/ 4","offer_id":46408572109039,"sku":"IEEJ-20250228C00701-007-PDF","price":330.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-KENKYUKAI_e3627d6a-d0f1-4c5d-93f9-ead53fa3fb84.png?v=1745232967","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-20250228c00701-007","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
