Abstract

Bir veya daha fazla nesnenin tespit edilmesi için bir radar sistemi sağlanmıştır. Radar sistemi, aynı anda bir CW radar sinyali ve bir FM-CW veya MF radar sinyali iletmek için bir radar dalga vericisini ve radar sisteminin bir tespit aralığında mevcut bir veya daha fazla nesneden yansıtılmış CW ve FM-CW veya MF radar sinyallerini almak için bir birinci radar dalga alıcısını içerir. Sistem ayrıca, birinci alıcı tarafından alınan CW iletim sinyallerini ve yansıtılmış CW sinyallerini karıştırmak için bir birinci CW karıştırıcısını ve FM-CW veya MF iletim sinyallerini ve karşılık gelen birinci alıcı tarafından alınan yansıtılmış FM-CW veya MF sinyallerini karıştırmak için bir birinci FM-CW veya MF karıştırıcısını içerebilir. Birinci CW karıştırıcısı, bir veya daha fazla birinci CW vuru sinyali üretmek üzere birinci alıcı tarafından alınan CW iletim sinyallerini ve yansıtılmış CW sinyallerini karıştırmak için bir karıştırıcı olabilir, her bir birinci CW vuru sinyali, bir nesnenin hızıyla ilgili olabilir ve birinci FM-CW veya MF karıştırıcısı, FM-CW iletim sinyallerini ve bir nesnenin mesafesi ve hızı ile ilgili bir veya daha fazla birinci FM-CW vuru sinyalini üretmek üzere birinci alıcı tarafından alınan yansıtılmış FM-CW sinyallerini karıştırmak için bir birinci FM-CW karıştırıcısı olabilir. Radar dalga vericisi, bir CW radar sinyalini ve bir FM-CW radar sinyalini eşzamanlı olarak iletmek için uyarlanabilir; burada FM-CW radar sinyali, bir rampa modülasyonlu sinyaldir. Radar sistemi ayrıca yansıtılmış CW ve FM-CW veya MF radar sinyallerini almak için birkaç radar dalga alıcısı içerebilir, alıcılar birinci ve/veya ikinci alıcı yönleri boyunca düzenlenebilir. Radar sistemi, farklı radar dalga alıcıları tarafından alınan karşılık gelen yansıtılmış radar sinyalleri arasındaki faz farklarını tespit etmek için araçlara sahip olabilir. Ayrıca bir veya daha fazla nesnenin radar tespit yöntemi sağlanmıştır; burada yöntem eşzamanlı olarak bir CW radar sinyali ve bir FM-CW veya MF radar sinyalinin iletilmesini ve bir birinci radar alıcısı vasıtasıyla yansıtılmış CW ve FM-CW veya radar sisteminin tespit aralığından bulunan bir veya daha fazla nesneden yansıtılmış MF radar sinyallerinin alınmasını içerir.
